Image Formats

Raster Image FormatVector Image Format
Raster (Bitmap)Vector
Pixel-based images with smooth colour blending. When enlarged, the image loses quality as pixels are randomly added.Objects with paths that can be scaled to any size without losing quality.
Web Use: 72ppi
Paper Printing: 300ppi
Large Format Printing: 200ppi
Common Use: Logos, illustrations, and technical drawings.

pdf-Portable Document FormatDOC-DocumentZIP-Archive File Format
PDFDOCZIP
File extension that can contain images, text formatting, interactive buttons, videos, embedded fonts, etc. This is an ideal format for printing since designers can manipulate pages, check the colour output, etc.Word process documents that should be exported as a PDF if the graphical information isn’t printing correctly.A lossless compressed archive file format that may contain multiple directories.
Common Use: Print or digital publishing.Common Use: Sending a large file over e-mail or USB stick.

First Order StochasticConventional HalftoneHalf Tint
First Order StochasticConventional Half-ToneFlat Tint
Creates the appearance of a wider gamut colour range. This is ideal for lighter colours to make them pop, however images will appear highly saturated with darker tones.Allows different tones in colour with varied dot size and fixed dot spacing.Fixed dot size and dot spacing.

Imposition

Layout the maximum amount of artwork pages on a sheet.

Printing Imposition: Repeat, gang run, and cut and stack

CMYK, RGB, & Spot Colours

Cyan, Magenta, Yellow, & Key: Digital printing colour model, also known as process colours.

Red, Green, Blue, & White: Additive colour model for electronic screens. Hexidecimal also represents RGB.

Spot Colours: Mixed ink that requires its own plate for offset printing.

CMYK, RGB, and Spot Colours/Pantone Swatches

Proofing Stages

Preflight, PrepressHard copy proof, colour matching, image/graphics visual check
PreflightHard Copy Proof
Our prepress follows a checklist to ensure that the file is print ready (images, document elements, colour plates, set-up for finishing, etc).Before the release of the whole job, our operator checks a hard copy proof to ensure there’s minimal mechanical inaccuracies, no graphical problems, and check the accuacy of colour.

Trapping

Misregistration, colour alignmentKnock-Out Printing, Black knock-out
MisregistrationKnock-Out
Happens due to various reasons such as instability of the imagesetter, final media, and the press. Often times you see this in newspapers. Although the operator can minimize inaccuracies, there will be some margin of error.This increases the gap for misregistration. If there’s no trapping or overprint set, automatically knock-out is set. Most digitally printed jobs use this method.
Spread TrappingChoke TrappingOverprinting
SpreadChokeOverprint
Light ink that overlaps into a dark background.Light background that spreads into a dark object.Generally used for black to overprint a light background. This creates a richer black.
