Print & Production

Busted

• Aqueous coating / varnishA thin clear liquid finish that seals printed ink and adjusts sheen without adding the thick plastic film of lamination.
• BleedExtra art running past the cut line so a slightly-off trim still lands in your design instead of leaving a white sliver.
• CaliperThe actual thickness of one sheet, not its weight. It decides how a card feels, how a fold behaves, and how wide a book spine becomes.
• CMYK vs RGBScreens mix light (RGB), presses mix ink (CMYK). Ink cannot reach the glowing colors a monitor can, so print comes back quieter.
• Coated vs uncoated stock; matte / satin / gloss finishCoated paper seals the surface so ink stays punchy; uncoated soaks it in and goes softer. Matte, satin and gloss set how much it shines.
• Color calibrationMeasuring and adjusting color devices to known targets so the screen, proof, and final print disagree as little as possible.
• Color profile / ICC profileA small file that tells software what a device's color numbers actually mean, so an image can be translated between screen, press and paper.
• Convert type to outlinesTurning live text into vector shapes so the file stops needing the font at all. Great for logos, terrible if you later need to fix a typo.
• Die cutCutting print into a custom shape with a blade bent to that outline, like a cookie cutter for paper: shaped stickers, windows, rounded tags.
• Dieline / cutting templateThe vector template showing where a printed piece gets cut, creased, and glued: a box drawn flat before anyone folds it.
• Digital stencil duplicator (Risograph/Riso)A stencil duplicator that makes cheap, bright, slightly misregistered prints with separate ink drums. The beloved Riso zine look.
• Digital vs offset printingDigital printing has almost no setup cost, so it wins at 50 copies. Offset burns metal plates: pricey to start, then cheapest by the thousand.
• Dot gainHalftone dots print larger or look larger than planned, so middle tones come off press darker and muddier than the file.
• Duplexed / two-ply stockTwo paper sheets bonded into one extra-thick stock, often mixing face colors or textures and turning the cut edge into part of the design.
• Edge paintingColor applied to a card's cut edges after trimming, turning the thickness into a visible accent. It works best on heavy or duplexed stock.
• Effective PPI / printer DPIHow many image pixels land in each printed inch. Scale a photo up in the layout and its effective PPI drops, so it prints soft.
• Flat size / finished sizeFlat size is the trimmed piece opened out; finished size is what remains after folding and final trimming. A4 folded once finishes at A5.
• Foil stampingMetallic film pressed onto paper with a heated die, so the logo shines like real metal instead of looking like flat gold ink.
• Fold typeThe named way panels fold and nest, such as gatefold, roll fold, or accordion. It decides panel widths, page order, and which side faces out.
• Font embeddingPacking font data inside a PDF so the printer sees the right typeface while the words stay live, searchable text.
• Four-color processFull-color printing made by layering halftone dots of cyan, magenta, yellow, and black ink instead of mixing a separate ink for every color.
• Gamut / out-of-gamutThe colors a device can reproduce. Out-of-gamut colors sit beyond that range, so conversion has to replace them with reachable ones.
• Grain directionThe direction most paper fibers run. Fold parallel to it for a clean bend; fold across it and thick stock can crack or spring open.
• Gutter / creep (shingling)The gutter keeps content out of the binding; creep is the outward page shift in a thick folded booklet that makes inner pages lose outer margin.
• Halftone screening / screen ruling (LPI)Turning photos into grids of larger and smaller dots so on-or-off ink can fake grey. LPI says how fine that dot grid is.
• ImpositionReordering pages on a press sheet so folding and trimming turn them back into a correctly numbered booklet or book.
• Ink coverage / TAC limitThe maximum combined CMYK ink allowed in one spot before the paper gets oversaturated, slow to dry, or prone to smearing.
• Kiss cut vs through cutKiss cut slices the peel-off sticker but leaves its backing sheet whole; through cut slices every layer into a loose shaped sticker.
• Large format / wide formatOversized printing for banners, posters, and signage, on rolls or rigid boards, where viewing distance lets you drop resolution hard.
• Letterpress; debossing; embossingLetterpress prints ink into a dent, debossing presses a shape down, embossing pushes it up. Finishes you feel with a thumb.
• Makeready / setup wasteThe time and throwaway sheets used to get a press aligned and on color before the first sellable copy. It makes short runs expensive.
• MoiréThe ghost pattern that appears when two fine grids overlap out of step: rescanned print, tight stripes, clashing halftone screens.
• Overprint vs knockoutKnockout punches a hole in the ink below so a color prints on bare paper; overprint prints on top and mixes with whatever is underneath.
• Pantone bridge / CMYK equivalentPantone's printed side-by-side guide to a spot color and its closest CMYK attempt, useful when a job must switch to four process inks.
• Paper grammage (gsm)How heavy a paper is, in grams per square meter. The number that decides whether your card feels flimsy or expensive.
• Paper stock / substrateThe actual material you print on: its weight, coating, color, and texture. Same file, different stock, completely different object.
• Perfect binding / saddle stitch / spiralThe three usual ways pages get held together: glued flat spine, folded and stapled through the middle, or a coil through punched holes.
• PreflightAn automated pass over your file that catches missing fonts, low-res images, stray RGB, and no bleed before the press does.
• PrepressEverything done to artwork after design and before press: color, bleed, resolution, fonts, proofs. The handoff, not the design.
• Press checkApproving the first live press sheets for color and registration before the printer commits the whole run.
• Print run / MOQThe run is how many copies get produced together; the MOQ is the fewest the printer will accept before setup stops making economic sense.
• Print-ready PDF (PDF/X)A PDF exported under a locked-down standard (PDF/X) that bakes in fonts, color, and bleed so the press sees what you saw.
• RegistrationHow exactly the separate ink layers line up. Off by a hair and edges get colored halos, like a badly printed comic book.
• Rich black vs 100% K blackFlat K-only black prints as washed-out grey over large areas. Rich black adds other inks underneath so it reads as truly deep black.
• Score / perforationA score is a pressed crease so thick paper folds without cracking; a perforation is a dotted line of tiny cuts so a piece tears off clean.
• Screen printingInk forced through a mesh stencil, one color at a time. It is the thick, punchy print used on T-shirts, posters, and signs.
• SeparationsThe artwork split into one printable channel per ink, such as four plates for CMYK plus one more for every spot color.
• SignatureOne press sheet folded into a bundle of pages, commonly 8, 16, or 32. Several signatures are gathered to make the book block.
• Simplex / duplex printingSimplex prints one face of a sheet; duplex prints front and back. Duplex also needs the right long-edge or short-edge flip direction.
• Soft proof / hard proofA soft proof simulates the printed result on a calibrated screen. A hard proof is the physical sample you hold before approving the run.
• Soft-touch / suede laminateA matte film that makes printed paper feel velvety or peach-soft while adding protection. The premium black-box feel.
• Spot color (for example, Pantone Matching System)A premixed named ink (like a Pantone number) printed on its own plate, so the brand color aims at one agreed target instead of a four-ink guess.
• Spot UVClear gloss varnish applied to chosen areas only, so the logo catches the light while the matte stock around it stays flat.
• TrappingA hairline overlap between printed colors that hides white gaps when the plates land a fraction out of alignment.
• Trim / safe areaTrim is where the blade lands. The safe area is the inner margin where your text is guaranteed to survive the cut.
• Trim marks; registration marksTrim marks are the corner lines showing where to cut; registration marks are the crosshair targets that check every ink plate lines up.
• UV coating / film laminationUV coating cures a liquid skin on the sheet; film lamination bonds on plastic. Laminate adds more protection, bulk, and tactile options.
• Variable data printingOne print design fed by a data file so every copy can carry a different name, image, offer, address, barcode, or QR code.
• Vector vs rasterVector art is math and stays sharp at any size; raster art is a fixed grid of pixels and turns to mush when you enlarge it.
• White ink / underbaseOpaque white ink laid under color so artwork stays bright on dark, colored, metallic, or transparent material.
