A

Absorbency

The rate at which a substrate (paper, board, fabric) takes up liquid ink or coating. High absorbency can mute colors and increase dot gain; low absorbency improves vibrancy but may lengthen drying. Matching ink chemistry to substrate absorbency is essential for predictable results and rub resistance in real-world handling.

Accordion Fold

A multi-panel fold that alternates in and out like a concertina. It’s ideal for brochures with steps, menus, or guides that unfold progressively. Designers must account for panel creep and ensure images and type align at folds to avoid cracking, misregistration, or text running too close to creases.

Acid-Free Paper

Lignin-free, pH-neutral paper designed to resist yellowing and deterioration over time. Preferred for archival printing, art reproductions, and museum-quality materials. Works well with pigment inks; pair with protective sleeves or conservation framing for longevity in display and storage.

Adhesive Label

A pressure-sensitive label printed on paper or film with a sticky back, supplied on sheets or rolls. Face stock, adhesive (permanent, removable, freezer), and liner selection matter. Used for products, logistics, and promotions; often paired with white ink and varnish/laminate for durability and scuff resistance.

Anilox Roller

In flexography, a laser-engraved ceramic roller that meters a precise ink volume to the plate. Cell counts and volumes control coverage and density. Cleanliness is critical; clogged cells reduce color strength and cause mottling or banding on press.

Anti-Aliasing

A rendering technique that smooths jagged edges in rasterized type and lines. Essential for on-screen previews; for print, ensure vector type remains live to keep edges sharp at any size and avoid unintended blurring from flattening.

Aqueous Coating

A fast-drying, water-based protective coating applied in-line on press. It enhances scuff resistance and adds a matte or gloss sheen with lower VOCs than many solvent finishes. Common on brochures, covers, folders, and packaging where durability, quick turnaround, and recyclability are priorities.

AR (Augmented Reality)

Technology that overlays digital content-video, 3D models, tutorials-onto the real world via a smartphone camera. Printed pieces include markers or QR codes that trigger experiences. Great for product demos, on-pack instructions, and events; plan artwork with clear calls-to-action and stable markers for tracking.

Archival Ink

Pigment-based inks formulated for long-term stability and fade resistance. Used in giclee fine-art printing and photo reproduction. Longevity depends on substrates, display conditions, and protective coatings or glazing.

Artwork

The final, production-ready design file supplied to the printer. It must include trim size, bleed (typically 3 mm), safe area, CMYK color, embedded/outlined fonts, high-resolution images (300 DPI), and correct overprint/knockout settings. Clean layers, linked assets, and PDF/X standards reduce prepress delays.

Assets

All components required to produce a print job: logo files, fonts, linked images, dielines, QR codes, profiles, copy, and usage licenses. Version control and clear naming conventions avoid mix-ups. Keeping assets centralized and brand-safe enables faster revisions, localized variants, and consistent quality across runs.

 

B

Backlit Film

Translucent film printed for lightboxes and menu boards. Colors are optimized for illumination from behind, requiring denser ink coverage and profiles. Finishing may include edge sealing or mounting in frames. Ideal for retail, airports, and hospitality where vibrant, evenly lit graphics are essential.

Backslit (Crack-and-Peel)

A slit on the label liner allowing easy removal without bending corners. Useful for hand application of stickers and product labels. Backslits can be vertical or horizontal depending on label size; specify placement to match application workflow and prevent liner tearing or waste during use.

Banding (Print)

Visible horizontal stripes or tone breaks caused by printer mechanics, ink delivery, or file issues. May appear in gradients and flat tints. Minimizing banding involves maintenance, correct profiles, adequate resolution, and designing gradients with noise or textures to reduce uniformity that reveals flaws.

Basis Weight

Weight of paper measured for a standard sheet size per industry convention. In many regions, GSM is clearer; basis weight varies by grade (e.g., text vs cover). Knowing both helps cross-compare specs with vendors.

Bindery

Post-press operations that assemble and finish printed sheets: folding, stitching, perfect binding, trimming, drilling, and more. Early planning with bindery ensures grain direction, creep, and fold allowances are correct. Good bindery prevents cracking and helps books open flat with durable spines.

Bitmap

A pixel-based image (raster). Enlarging beyond 100% at print size degrades sharpness. Provide photographs at 300 DPI and avoid upscaling small web images. For logos and icons, use vector formats to maintain crisp edges across sizes, substrates, and finishing processes such as foil or varnish.

Blanket (Offset)

The compressible rubber surface that transfers ink from plate to paper in offset printing. Blanket condition affects dot reproduction and solids; proper packing, cleaning, and replacement intervals preserve quality and minimize hickeys.

Bleed

Extra artwork extending beyond the trim (commonly 3 mm) to prevent white edges after cutting. Include crop marks and keep text within the safe area. Bleed is essential for borderless images, edge-to-edge color, and designs with backgrounds or patterns that must reach the final edge cleanly.

Blister Pack

A thermoformed plastic cavity sealed to a printed card, often with a hang hole for retail display. Artwork must consider sealing zones and visibility of the product. Increasingly subject to sustainability scrutiny; paper-based and recyclable options are expanding to meet EPR and retailer requirements.

Blueline

A historical proofing method that produced a low-cost mono proof showing layout and pagination. Today, digital soft proofs and calibrated contract proofs largely replace bluelines, but the concept remains: verify sequence, trim, and content before committing to plates, paper, and full production costs.

Bounce (Screen Printing)

Slight vertical movement of the screen during printing, often causing image blur or double imaging. Minimized by proper off-contact distance, flood/print stroke balance, and stable press setup.

Boxboard

Sturdy paperboard used for cartons, sleeves, and rigid packaging. Grades vary by recycled content, brightness, and coating. Structural performance depends on caliper and grain direction. Pair with lamination, varnish, or foil for shelf impact, while balancing EPR/recyclability goals in target markets.

Bulk (Paper)

The perceived thickness or stiffness of paper relative to its weight. High-bulk papers feel more substantial at lower GSM, improving tactile quality and opacity without increasing mailing costs significantly.

 

C

Chlorine-Free (ECF/PCF)

Paper bleached without elemental chlorine (ECF) or processed chlorine-free with recycled fiber (PCF). Selected to reduce dioxin concerns and meet sustainability standards or corporate procurement policies.

CMYK (Process Color)

Cyan, Magenta, Yellow, and Black inks combine via halftone screens to reproduce full-color images. Limited gamut vs RGB; saturated greens, oranges, and neons may dull. Use profiles, rich blacks, and spot colors for brand-critical hues.

Coated vs Uncoated

Coated papers have a clay surface for sharper images and higher contrast; uncoated stocks offer a tactile, writable feel with softer color. Choose based on brand tone, readability, and finishing needs. Uncoated often suits stationery; coated excels in photo-heavy marketing.

Coating Weight

The amount of coating applied to paper (g/m2). Influences gloss, ink holdout, and stiffness. Higher weights yield smoother surfaces for high-resolution imagery but can affect foldability and cracking risk.

Coil Binding

A continuous plastic or metal coil threaded through punched holes, allowing pages to turn 360 degrees and lay flat. Durable for manuals and cookbooks; requires margin allowances near the spine to prevent hole punching through text.

Collate

Arranging pages into the correct sequence during finishing. Automated collators reduce manual errors and speed assembly. Proper collation matters when inserts, tabs, or mixed stocks are present to keep sets accurate and press-ready.

Color Bar

A control strip printed at the sheet edge containing patches for density, gray balance, and registration checks. Press operators measure it with densitometers or spectrophotometers to maintain consistency across the run and identify issues early.

Color Gamut

Convert (Converting)

Turning printed or plain materials into finished products-die-cutting, folding, gluing, slitting, and laminating. Converters finalize packaging formats like cartons, sleeves, and pouches to spec.

Creep

In saddle-stitched booklets, inner pages extend outward as they fold, shifting margins at the fore-edge. Designers compensate by progressively nudging content inward so headlines and page numbers don’t trim off.

Crop Marks

Fine lines indicating final trim around the page. Combined with bleed and registration marks, they guide cutting equipment. Keep critical content away from the trim to avoid accidental cropping.

CTP (Computer-to-Plate)

Workflow imaging printing plates directly from digital files-faster and more accurate than film. Standard in offset production for tight registration, sharp halftones, and reliable long runs.

Curl

Unwanted bending of paper due to moisture imbalance, grain direction, or uneven coatings. Causes feeding issues and poor lay-flat performance; manage through conditioning, correct grain, and balanced finishes.

Cyan

One of the CMYK primaries. Balanced cyan density is crucial for clean skies, aquas, and neutrals. Monitor cyan gain on uncoated stocks where absorbency can mute color.

Deckle Edge

A feathery, irregular paper edge that mimics hand-made sheets. Adds artisanal character to invitations and art prints. Plan trims and layouts so the effect looks intentional and doesn’t interfere with readability or folding.

Densitometer

Instrument measuring optical density of inks and tints on paper. Used on color bars to control solid densities, dot gain, and gray balance during press runs for consistency.

Density (Optical)

How much light a printed area absorbs. Higher density equals darker print. Target densities vary by stock and standard; consistent density improves image contrast and repeatability.

Descender

The part of a lowercase letter that falls below the baseline (e.g., g, j, p, q, y). Typography should allow adequate leading so descenders don’t clash with ascenders on the line below.

Die Cut

Cutting paper or board into custom shapes using a metal die. Essential for folders, windows, stickers, and shaped packaging. Follow dielines, allow tolerances, and avoid tiny slivers that can break during stripping.

Die Line Tolerance

Mechanical allowance around cuts and scores to accommodate converting variation. Artwork should avoid placing hairline elements directly on cuts; add bleed and safe areas per spec to maintain clean results.

Dieline

A vector template showing cut lines, folds, scores, bleed, and glue zones for packaging. Accurate dielines ensure print aligns with structure, speeding approvals and assembly while preventing fit issues on shelves or machines.

Digital Printing

Printing directly from digital files, ideal for short runs, quick turnarounds, and personalization without plates. Color consistency often rivals offset, with lower setup. Perfect for targeted campaigns, micro-batches, and rapid prototyping across substrates. Read more: Digital Printing.

Dot Gain

The tendency for halftone dots to print larger than intended due to ink spread and absorbency, darkening tones. Managed by calibration, appropriate curves, and paper/ink choices. Excessive gain reduces detail and shifts colors toward muddy neutrals.

Dot Pitch (Display)

Distance between pixels on a monitor. Smaller pitch yields sharper previews, but print decisions should rely on resolution at size and profiles-not screen appearance alone.

DPI / PPI

A measure of image resolution. For crisp print, supply photos at 300 DPI at final size. Web images (72-144 PPI) often look soft. Vector artwork scales cleanly; raster should be checked before enlarging.

DPI vs LPI

DPI describes image resolution; LPI describes halftone screen frequency. Matching source DPI (~2x LPI) helps avoid detail loss: e.g., 300 DPI images for 150 LPI offset work.

Drilling

Punching holes for binding, clips, or hang tags. Specify hole size, position, and pattern (e.g., 2-hole, 3-hole). Consider paper weight and backing sheets to reduce burring and heat.

Polybag

A plastic bag used for packaging or mailers. May be clear or printed, with suffocation warnings and reclosable features. Shifting regulations favor recyclable or paper-based alternatives for sustainability.

PPI vs DPI

Pixels per inch describes image data; dots per inch describes output device capability. For print, supply ~300 PPI at size; higher PPI seldom improves results if the printer cannot resolve it.

Preflight

Automated checks ensuring files are print-ready: resolution, color mode, fonts, bleed, overprint, and linked images. Catching issues early prevents costly delays and reprints.

Press Check

Client or designer reviews the first sheets on press to verify color and registration before approving the full run. Useful for high-value jobs; decisions should be made under standardized lighting.
