Frequently Asked Questions

By Pritesh Yadav June 21, 2026 9 min read —

These are the questions a software builder almost always asks when they first start modeling print. The answers are deliberately plain-English and practical. Where it helps the person building the SaaS, we note what to capture in your data model.

What is the difference between offset and digital printing, and when is each cheaper?

Offset presses transfer ink from metal plates onto a rubber blanket and then onto paper. Making those plates and "tuning" the press (called make-ready) costs time and money before a single good sheet comes out — but once running, each extra sheet is very cheap. Digital printing (toner or inkjet) has almost no setup; it prints like a giant office printer, so the cost is roughly the same per page whether you print 1 or 500.

Rule of thumb: short runs are cheaper digital; long runs are cheaper offset. The crossover for typical color jobs sits somewhere around 500–1,500 copies, depending on size, paper and shop. Below that, go digital; well above it, go offset.

Why doesn't the color on my screen match the printed piece (RGB vs CMYK)?

Your screen makes color by emitting light and mixes Red, Green, Blue (RGB) — that's an additive system, and bright glowing colors are easy. Print makes color by laying down ink that absorbs light and mixes Cyan, Magenta, Yellow, Black (CMYK) — a subtractive system. CMYK simply can't reproduce some of the vivid blues, greens and oranges a screen can glow. So a neon screen blue prints duller. This is normal physics, not a bug.

The fix is to design and proof in CMYK, use a color profile (like GRACoL or FOGRA) so everyone shares the same target, and warn customers in software when their uploaded file is RGB.

What is GSM and how do I pick paper?

GSM = grams per square meter — the weight of one square meter of the paper. Higher GSM generally means thicker, stiffer, more premium-feeling stock. It is the cleanest way to specify paper because it doesn't depend on sheet size (unlike the US "pound" system, which does).

80–120 gsm — letterhead, copy paper, cheap flyers.
130–170 gsm — quality flyers, posters, magazine pages.
200–300 gsm — postcards, menus, light covers.
300–400 gsm — business cards, premium cards, packaging.

What is bleed, and why do print files need it?

Bleed is extra image area that extends past the final trimmed edge — usually 3 mm (about 0.125 in) on each side. Cutting blades and folded sheets shift by tiny amounts, so if your background color stopped exactly at the edge, you'd get thin white slivers. Bleed gives the cutter a safety margin so ink runs all the way to the edge.

There are three zones: the bleed (cut into), the trim (the final size), and the safe zone (keep important text ~3 mm inside the trim so it isn't sliced off). Your preflight code should check that uploaded files include bleed.

What does "4/4" or "4/0" mean?

It's printer shorthand for ink colors front / back. The "4" means full-color CMYK (4 inks). So:

4/4 = full color both sides.
4/0 = full color front, nothing on the back.
1/0 = one ink (e.g. black) on front only.
4/1 = full color front, black-only back (common for flyers).

In software, model this as two fields: front_colors and back_colors — it drives both pricing and plate/press setup.

What is a gang run?

Ganging means combining several different jobs (from different customers) onto one big press sheet so they share the same make-ready and run together. It slashes per-job setup cost, which is why online "trade printers" can sell 500 business cards so cheaply. The trade-off: ganged jobs run on standard sizes/stocks and on the shop's schedule, so you give up customization and speed control.

How is a print job actually priced?

A quote is usually built from layers:

Setup / make-ready — fixed cost per job (plates, press tuning, file prep). Spread across the run.
Materials — paper/substrate + ink, scaled by quantity and size.
Running / click cost — press time (offset) or per-impression "click" charges (digital).
Finishing — cutting, folding, binding, lamination, etc.
Overhead + margin — the shop's profit and fixed costs.

Because setup is fixed, the per-unit price drops as quantity rises. That's why print uses quantity-tier pricing, not a single unit price.

What is make-ready and why does it cost so much?

Make-ready is all the work to get a press ready to produce good sheets: mounting plates, loading paper, balancing ink and water, and running waste sheets until color is correct. It is mostly a fixed cost per job and is the single biggest reason short runs are expensive on offset. Digital printing has almost no make-ready, which is its core advantage.

What finishing options should my product page offer?

Offer the common, high-demand ones and tie each to a price modifier:

Lamination / coating — gloss, matte, or soft-touch (protects and changes feel).
Folding — half, tri-fold, gate, etc. (for brochures).
Binding — saddle-stitch (stapled), perfect bound (glued spine), spiral/wire.
Cutting / shaping — round corners, die-cut shapes.
Embellishments — foil stamping, embossing, spot UV (premium upsells).
Drilling/holes, scoring, perforation — for hang tags, tear-offs, easy folds.

In software, model finishing as a list of selectable options, each with its own pricing rule and any constraints (e.g. saddle-stitch needs page count divisible by 4).

What is preflight?

Preflight is the automated check of a customer's file before it goes to press — like a spell-checker for print. It verifies bleed, resolution (DPI), color mode (CMYK vs RGB), embedded fonts, correct page size, and overprint settings. Good preflight catches problems early so you don't print 5,000 flawed pieces. For a SaaS, preflight-on-upload is one of the highest-value features you can build.

What is DPI / resolution and what number do I need?

DPI (dots per inch) measures how much detail an image holds at its print size. Too few dots and the image looks blurry or blocky ("pixelated"). The press standard is 300 DPI at final print size for photos. Large signage viewed from far away can use far less (72–150 DPI) because distance hides the dots. Your uploader should compute effective DPI from pixel dimensions vs placement size and warn if it's too low.

What is a Pantone (spot) color and when do I need one?

CMYK builds colors by overlapping four inks, which can drift batch to batch. A Pantone / spot color is a single pre-mixed ink with a standardized recipe (PMS number) — so a brand red is identical everywhere. You need spot colors for brand consistency, metallics, fluorescents, or colors CMYK can't reach. They add a press unit and cost, so they're a paid option, mostly on offset.

What's the difference between DTG, DTF and screen printing for apparel?

Method	How it works	Best for
Screen printing	Ink pushed through a stencil/mesh, one screen per color	High volume, few colors, durable
DTG (direct-to-garment)	Inkjet prints directly onto fabric	Full-color, photo designs, low quantities
DTF (direct-to-film)	Print on film, then heat-press transfer	Many fabric types, small batches, vivid color

Screen printing has setup cost per color (like offset's make-ready), so it wins at volume. DTG and DTF have little setup, so they win for one-offs and full-color art.

Parcel vs freight shipping — what's the difference?

Parcel is individual boxes shipped via carriers like UPS/FedEx/USPS — fine for small, light orders. Freight (often LTL, "less-than-truckload") is for heavy or bulky shipments on pallets — large poster runs, boxes of catalogs, signage. The break point is usually around 68–70 kg (150 lb) or when goods are palletized. Carriers also charge by dimensional weight (size, not just actual weight) for light-but-bulky items, so a big box of foam signs can cost more than its scale weight suggests.

What is dimensional (volumetric) weight?

Carriers bill the greater of actual weight or a calculated size-based weight, because a truck fills up by space, not just by mass. Typical formula: (L × W × H in cm) ÷ 5000 = dim weight in kg (the divisor varies by carrier and units). Light, bulky print (banners, foam board, packaging) is often billed on dim weight. Your shipping estimator must store box dimensions, not just weight.

Is digital printing eco-friendly?

It depends, but generally digital is greener for short runs because it skips plates and make-ready waste, prints on demand (less overproduction and obsolete inventory), and supports print-only-what-you-sell. Offset can be greener at high volume per unit. Bigger sustainability levers than process choice: using FSC-certified or recycled paper, vegetable/soy-based inks, water-based or UV-LED curing, right-sizing quantities to cut waste, and efficient nesting/imposition. "Eco" claims should be backed by certifications, not vibes.

What production statuses should an order move through?

A clean, plain-language status spine customers understand:

Order Received → File Check (Preflight) → Approved / Proof Sent → In Production → Finishing → Quality Check → Shipped → Delivered

Add side states for Action Needed (bad file, awaiting proof approval), On Hold, and Cancelled/Refunded. Each transition is worth logging (who, what, when) for support and disputes.

What is imposition and batching?

Imposition is arranging multiple pages or copies on one large press sheet so that, after printing and folding/cutting, everything ends up in the right order and orientation. Batching groups similar jobs (same stock, same size, same color setup) to run together and share setup. Both exist to cut waste and setup cost. In software you don't have to do imposition math, but you should capture the attributes (size, stock, color, finishing) that let a shop batch efficiently.

What's the difference between margin and markup?

They sound the same but aren't. Markup is profit as a percentage of cost. Margin is profit as a percentage of the selling price. A 50% markup is only a 33% margin. Mixing them up is a classic costing mistake that quietly erodes profit. Pick one convention in your pricing engine and label it clearly.
