Design software: Adobe tools

In short

Adobe's Creative Cloud is the standard toolchain for communication, product and fashion design work in India: Photoshop for raster images, Illustrator for vector artwork, InDesign for multi-page layout, Premiere Pro and After Effects for motion, and Lightroom for photographic workflow. A B.Des student is examined on the *concepts* the software encodes — raster versus vector, resolution, colour models, colour management, layers and masks, type anatomy, and print-ready output — not on menu paths. These appear in Communication Design and Digital Media papers, in NID/CEED-style objective questions, and above all in portfolio reviews and software tests at placement, where studios ask candidates to redraw a logo, retouch a product shot or hand over a press-ready PDF. Indian employers (Ogilvy, Leo Burnett, Wunderman Thompson, Lowe Lintas, Titan, Asian Paints, Flipkart, Zomato, Decathlon India, Raymond, Aditya Birla Fashion) treat fluency in Photoshop, Illustrator and InDesign as a baseline and Figma as the UI companion. Licensing, fonts and image rights are examined too, under the Copyright Act, 1957 and the Designs Act, 2000.

Explained

Raster and vector: the core distinction

• Raster (bitmap): a grid of pixels, each with a colour value. Scaling up interpolates and blurs — resolution is fixed at creation. Photoshop, Lightroom, Fresco are raster-first.
• Vector: mathematical paths (anchor points, Bézier handles), fills and strokes. Resolution-independent — a logo scales from a 12 mm shirt tag to a 12 m hoarding with no loss. Illustrator is vector-first.
• When to use which: photographs, textures, digital painting, fabric prints with photographic detail → raster. Logos, icons, type-based artwork, technical and apparel flats, packaging dielines, cutting/embroidery files → vector.
• Bit depth: 8-bit/channel = 256 levels per channel (≈16.7 million RGB colours); 16-bit gives smoother gradients and survives heavy editing; 32-bit for HDR. Higher depth = larger files.
• Colour channels: greyscale 1 channel, RGB 3, CMYK 4; alpha channel stores transparency.
• File formats:
  • Raster lossless/editable: PSD, TIFF, PNG (transparency, 8/24-bit), BMP.
  • Raster lossy: JPEG (DCT compression, artefacts at low quality, no transparency), WebP/AVIF (better compression, web).
  • Vector/page: AI, SVG (web vector, XML-based), EPS (legacy), PDF (hybrid — can carry vector, raster and type).
  • Camera RAW (CR3, NEF, ARW, DNG): unprocessed sensor data, maximum latitude; DNG is Adobe's open archival RAW.

Resolution, size and print geometry

• PPI vs DPI: pixels per inch describes the image file; dots per inch describes the printing device. Loosely interchanged, but exam answers should distinguish them.
• Standard effective resolutions: 300 ppi for offset/press work, 150–200 ppi for large-format posters and flex (viewed from a distance), 72–150 ppi for screen (CSS px with @2x/@3x assets for mobile).
• Resampling: *Image Size* changes pixel count (destructive); changing only the ppi with resampling off changes print size, not data. *Canvas Size* adds or crops working area without scaling content.
• Bleed, trim, safe margin: artwork extends 3 mm (Indian and international practice) beyond the trim line as bleed; keep text at least 5 mm inside trim as the safe area. Crop marks and registration marks guide cutting and plate alignment.
• Paper and sizes: ISO A-series (A4 = 210 × 297 mm, A3 = 297 × 420 mm) — each step halves the area, aspect ratio 1:√2. Indian print buying quotes paper in GSM (grams per square metre): 70–100 gsm text/letterhead, 130–170 gsm brochure, 250–350 gsm visiting card and packaging board.
• Imposition, gutter, creep matter for booklets; InDesign handles spreads and the printer handles imposition.

Colour: models, gamut and management

• RGB (additive): emitted light, for screens. CMYK (subtractive): inks on paper, with K (key/black) for depth and economy. Conversion loses saturated RGB colours — bright screen blues and greens print duller; always design print jobs in CMYK or soft-proof.
• Spot colour: a premixed ink (Pantone/PMS) printed from its own plate — used for exact brand colours, metallics and fluorescents that CMYK cannot reach. Each spot plate adds cost, so most Indian commercial jobs are 4-colour process, with 1–2 spots for premium packaging.
• Other models: HSB/HSL (hue, saturation, brightness — intuitive for picking), Lab (device-independent, used internally for conversion), greyscale, duotone.
• Colour profiles (ICC): sRGB for web and most Indian client deliverables; Adobe RGB (wider) for photography; ProPhoto RGB for archival RAW work; ISO Coated / Coated FOGRA or a press-supplied profile for offset. Indian presses commonly ask for CMYK, 300 ppi, with their own profile — confirm before export.
• Rendering intents: Perceptual (photographs — compresses whole gamut), Relative Colorimetric (logos/brand colour, clips out-of-gamut), Saturation, Absolute Colorimetric (proofing).
• Total ink limit / TAC: around 300–320% for coated offset; rich black is typically about C40 M30 Y30 K100, never 4×100%. Small text and hairlines are printed in 100% K only, to avoid misregistration.
• Overprint and knockout, trapping: overprinting black text avoids white fringes at register errors.

Photoshop: non-destructive raster workflow

• Layers stack with opacity, blend modes (Multiply darkens, Screen lightens, Overlay/Soft Light for contrast), and layer order.
• Smart Objects: embed or link source art so transforms and filters stay re-editable; Adjustment layers (Curves, Levels, Hue/Saturation, Colour Balance) edit tonality without touching pixels.
• Masks: a *layer mask* is greyscale — white reveals, black conceals, grey is partial; a *clipping mask* limits one layer to another's shape; *vector masks* use paths. Masking beats erasing because it is reversible.
• Selections: marquee/lasso, Object Selection and Select Subject (AI-assisted), Colour Range, Quick Mask, channel-based selections for hair and fabric; refine with feather and Select & Mask.
• Retouching: Clone Stamp (copies pixels), Healing Brush and Spot Healing (blends texture with surrounding tone), Patch, Content-Aware Fill, Frequency Separation for skin and fabric texture, Generative Fill for extending backgrounds.
• Transform and warp: Free Transform, Perspective Warp, Puppet Warp; displacement maps and Smart Objects for mockups — standard for placing a print on a garment or label on a bottle.
• Camera Raw / Lightroom: exposure, white balance, lens correction, calibration — all parametric and reversible; Lightroom adds cataloguing, keywords and presets for shoots.
• Output: *Save for Web / Export As* for PNG-24, JPEG quality 60–80, WebP; *Save As* PSD/TIFF for archives.

Illustrator and InDesign: vector and layout

• Pen tool and Béziers: anchor points with direction handles; corner vs smooth points. Place few anchors, at extremes of curves, handles roughly one-third of the curve length — the single most tested craft skill in Illustrator tests.
• Core vector operations: Pathfinder (unite, minus front, intersect, exclude), Shape Builder, Offset Path, Outline Stroke, Expand, Compound Path (holes in letters), Clipping Mask, Blend, Gradient Mesh, Image Trace (raster → vector), Live Paint.
• Precision tools: Artboards (multiple sizes in one file), rulers, smart guides, Align/Distribute, Transform Each, Symbols, Graphic Styles, Global swatches (edit once, update everywhere), Recolor Artwork (fast colourway generation for fashion ranges).
• Strokes: weight in pt, caps and joins, dashes, variable-width profiles, arrowheads; apparel flats and packaging dielines use defined stroke/spot colours for cut, crease and perforation lines.
• Type: point type vs area type, Type on a Path, Create Outlines (converts type to vector — do it only on a copy, as text is no longer editable).
• InDesign for multi-page: Master/Parent pages, baseline grid, Paragraph and Character Styles, text threading, Data Merge, Table styles, footnotes, Book files, Preflight panel, Package (collects links and fonts), and PDF/X-1a or PDF/X-4 export for press.
• Division of labour: Illustrator for the mark and illustration, Photoshop for imagery, InDesign for anything with flowing text and many pages. Catalogues, annual reports and magazines are laid out in InDesign, not Illustrator.

Typography, motion and the wider suite

• Type anatomy and metrics: baseline, x-height, cap height, ascender, descender, counter. Point size (1 pt = 1/72 inch), leading (line spacing — body text about 120–145% of size), tracking (uniform letter spacing, in 1/1000 em), kerning (pair-specific spacing), measure (about 45–75 characters per line).
• Font formats and Indian scripts: OpenType (OTF/TTF), variable fonts (continuous weight/width axes), and OpenType features (ligatures, small caps, oldstyle figures). Devanagari and other Indic scripts need shaping/conjunct support — use Adobe's World-Ready Composer and Indic-capable fonts (Adobe Devanagari, Noto, Mukta, Ek Mukta); Unicode encoding, not legacy Kruti Dev/Shree Lipi.
• Motion and video: Premiere Pro (editing, timeline, proxies, Lumetri colour, captions), After Effects (compositing, keyframes, masks, rotoscoping, expressions, Puppet tool rigs; Character Animator for 2D character animation), Media Encoder (H.264/H.265 delivery), Audition (audio). Reels/Shorts deliverables are 1080 × 1920 (9:16), 1080 × 1080 (1:1) for feed, 1920 × 1080 (16:9) for YouTube; 24/25/30 fps common in India (PAL legacy = 25 fps).
• Others in the stack: Adobe XD (UI/prototyping — now minimal further development, with Figma dominant), Acrobat Pro (PDF preflight, accessibility tagging), Dimension and Substance 3D (product renders, materials), Fresco, Express, Firefly (generative imagery), Adobe Fonts, Creative Cloud Libraries (shared colours, type, logos across apps and team).
• Pricing and licensing (India, indicative — verify current rates): Creative Cloud All Apps for individuals is of the order of ₹4,000–₹5,000 per month plus GST at 18%, single apps roughly ₹1,500–₹2,000 per month; discounted student/teacher and lower-cost Photography plans exist. Rates change — check Adobe India's site. Institutional labs use named-user device/team licences.
• Legal and ethical points: software piracy is an infringement of copyright in a computer programme under the Copyright Act, 1957 (as amended); fonts and stock images are licensed, not bought — honour the licence (Adobe Stock, Shutterstock, or CC0 sources). A logo is protected as an artistic work under copyright and as a trade mark under the Trade Marks Act, 1999; a product's shape/surface ornamentation is registrable under the Designs Act, 2000. GST on software subscriptions follows the standard 18% rate (slabs since 22 September 2025 are 5%/18%/40%).

Key points

• Raster - pixel grid, resolution-dependent, for photographs; vector - Bézier paths, scalable infinitely, for logos and flats.
• 300 ppi at final print size - the offset benchmark; 150–200 ppi is adequate for large-format viewed from a distance.
• RGB additive for screens, CMYK subtractive for ink - always convert and soft-proof before sending a press job.
• Spot (Pantone) colour - a premixed ink on its own plate for exact brand colour; each spot adds cost.
• Bleed 3 mm, safe margin ~5 mm - artwork past the trim line prevents white slivers after cutting.
• ICC profile - describes a device's colour behaviour; sRGB for web, Adobe RGB for photography, press profile for offset.
• Layer mask - greyscale, white reveals / black conceals; reversible, unlike the eraser.
• Smart Object + adjustment layer - the basis of non-destructive Photoshop editing.
• Healing Brush vs Clone Stamp - healing blends texture with surrounding tone; cloning copies pixels exactly.
• Pathfinder, Compound Path, Clipping Mask - combine, cut holes in, and crop vector art.
• Create Outlines - converts live type to shapes; safe for press, fatal for later text edits.
• Global swatch / Recolor Artwork - change one swatch and every instance updates; fast colourways for a range.
• InDesign Parent pages + Paragraph Styles - consistency across a multi-page catalogue; Package collects fonts and links.
• PDF/X-1a vs PDF/X-4 - X-1a flattens and forces CMYK; X-4 keeps live transparency and colour management.
• GSM - paper weight in g/m²; 300–350 gsm for visiting cards, 130–170 gsm for brochures.
• Rich black ≈ C40 M30 Y30 K100; small text and hairlines in 100% K only to avoid misregistration.
• Total ink limit ~300–320% on coated stock; exceeding it causes set-off and drying problems.
• File size ≈ pixels × channels × bit depth; doubling ppi quadruples the data.

Formulas and examples

Example 1 — Pixels needed for an A3 poster at press quality. A3 = 297 × 420 mm → 297/25.4 = 11.693 in, 420/25.4 = 16.535 in. At 300 ppi: 11.693 × 300 = 3,508 px and 16.535 × 300 = 4,961 px → about 3,508 × 4,961 px. Uncompressed CMYK 8-bit: 3,508 × 4,961 × 4 × 1 = 69,612,752 bytes ≈ 66.4 MB (69.61 MB decimal). With 3 mm bleed the InDesign document is 303 × 426 mm.

Example 2 — Is a camera file big enough for a hoarding? A 24 MP file is 6,000 × 4,000 px. A flex hoarding of 10 ft × 6.67 ft = 120 in × 80 in. Effective resolution = 6,000/120 = 50 ppi (and 4,000/80 = 50 ppi). Acceptable for a hoarding viewed from 15–20 m, where 30–50 ppi is normal practice; unusable for a 300 ppi brochure. Same file printed at A4 (8.27 × 11.69 in): 6,000/11.69 ≈ 513 ppi — more than enough, and can be downsampled to 300 ppi.

Example 3 — Resizing without resampling. An image is 2,400 × 3,000 px at 300 ppi → print size 8 × 10 in. The client wants it at 12 in tall. New ppi = 300 × (10/12) = 250 ppi — still printable for offset at a push, fine for digital print. Resampling up to 300 ppi at 12 in would need 3,600 px tall, i.e. inventing 20% more data.

Example 4 — Typography and line count. Body text 10 pt with 1.3 leading → leading = 10 × 1.3 = 13 pt. A text frame 180 mm tall = 180/0.3528 ≈ 510 pt → 510/13 ≈ 39 lines per column. At 65 characters per line that is about 2,535 characters ≈ 420 words per column.

Example 5 — Print paper cost for a brochure run. 2,000 copies of an 8-page A4 brochure on 170 gsm art paper. 8 A4 pages = 4 A4 leaves = 2 A3 sheets per copy (printed both sides). Sheets needed = 2,000 × 2 = 4,000 A3 sheets. A3 area = 0.297 × 0.420 = 0.12474 m² → weight per sheet = 0.12474 × 170 = 21.206 g. Total paper = 4,000 × 21.206 g = 84,823 g ≈ 84.8 kg. At ₹110/kg → ≈ ₹9,331 for paper, before plates, printing, lamination, binding and 18% GST.

Interview questions

• Q: When would you choose Illustrator over Photoshop for the same artwork? A: When the artwork must scale without loss or be output to a cutter/press as paths — logos, icons, type-led designs, dielines and apparel flats; Photoshop is for photographic and texture-based pixel work.
• Q: A client sends a 72 ppi JPEG for a hoarding. What do you do? A: Check the pixel dimensions, not the ppi — ppi is only metadata. Compute effective resolution at the final size; if it falls below about 30–50 ppi for a hoarding, ask for the original or re-create the asset as vector rather than upscaling.
• Q: Why does a bright screen colour look dull in print? A: RGB is additive light with a wider gamut than CMYK inks; saturated blues, greens and oranges fall outside the CMYK gamut and get mapped inward during conversion. Soft-proof with the press profile, or use a spot colour.
• Q: What is bleed and why 3 mm? A: Artwork extended beyond the trim line so that cutting tolerance never leaves a white edge; 3 mm is the standard allowance in Indian and international commercial print.
• Q: Difference between a layer mask and a clipping mask? A: A layer mask is a greyscale channel controlling that layer's own visibility; a clipping mask uses one layer or path to constrain another layer's visible area to its shape.
• Q: Clone Stamp or Healing Brush for removing a blemish? A: Healing Brush — it blends the sampled texture with the surrounding tone and colour; Clone Stamp copies pixels verbatim and tends to leave visible patches on gradients like skin.
• Q: What does Create Outlines do, and what is the risk? A: It converts live text into vector shapes so no font is needed downstream; the text can no longer be edited or spell-checked, so keep an editable master file.
• Q: PDF/X-1a or PDF/X-4 for an offset job? A: X-1a if the press wants everything flattened and in CMYK — the safest legacy choice; X-4 if they support live transparency and colour management, which keeps better quality. Always ask the printer first.
• Q: How do you make a 48-page catalogue consistent? A: InDesign with parent pages, a baseline grid, paragraph/character styles, library-linked brand swatches and logos, then Preflight and Package before sending.
• Q: What is rich black and when is plain K used? A: Rich black adds CMY under 100% K (about C40 M30 Y30 K100) for deep large areas; small text and thin rules use 100% K only, because four plates cannot register perfectly at that size.
• Q: How would you place a print design on a T-shirt photo convincingly? A: Place the artwork as a Smart Object, warp it to the garment, set the blend mode to Multiply or use a displacement map from the fabric's luminosity so folds and texture show through, then mask the edges.
• Q: Non-destructive editing — what does it mean in practice? A: Edits stay re-editable: Smart Objects, adjustment layers, masks instead of erasing, Camera Raw/Lightroom parametric settings, linked files, and effects applied as layer styles rather than baked into pixels.
• Q: Which colour profile do you deliver web assets in? A: sRGB, embedded, with Convert to sRGB on export — other profiles shift colour in browsers and on phones.

Common mistakes

• Judging an image by its ppi field instead of its pixel dimensions — ppi alone means nothing without the output size.
• Designing print artwork in RGB and converting at the end, then being surprised by dull colours; or designing web assets in CMYK.
• Forgetting bleed and safe margins, so text is clipped or a white sliver appears after trimming.
• Upscaling a small raster image and calling it a fix; the right answer is a bigger source or a vector rebuild.
• Erasing pixels and flattening early instead of masking and using Smart Objects — no way back when the client changes the brief.
• Laying out a multi-page document in Illustrator or Photoshop; there is no text flow, no styles and no reliable preflight.
• Sending a packaged job without outlining type or including fonts and linked images, so the press substitutes fonts and links go missing.
• Using 4×100% CMYK as "black" or ignoring the total ink limit, and setting 6 pt text in four colours.
• Confusing kerning with tracking in an exam answer — kerning is pair-specific, tracking is uniform.
• Using pirated software or unlicensed fonts and stock images for commercial work, which is infringement under the Copyright Act, 1957.
