Print Media- Test 2

7 Consideration of Production Planning

Audience, purpose, use, quality, quantity and other processes, scheduling

gital/On-demand vs. Off set lithography printing For quantities under 1000 a digital press may be more economical.

Digital/On-demand presses are roughly the same cost per unit regardless of the quantity, Cost per unit refers to the individual cost of an item after a large quant has been printed. The higher the quantity, the lower the per unit cost

Line can should be how many dpi.

1200 dpi

Psd- native photoshop document

• this is usually your layered (or unflattened) file before you save to another format.

• work in this while you’re making changes, then change to appropriate file type for your output

tiff- Tagged Image File Format

• the American National Standards Institute (ANSI) and International Standards Organization (ISO) preferred format for printing

• RIPS’s same on any equipment

  • LZM compression (Lempel Ziv Welch)

    • Lempel Ziv Welch which is a compressed image (lossless data algorithim) is same as original when decompressed (no image loss) (ZIP is a form of LZW)

eps- Encapsulated Post Script

• contains bitmap information for preview image.

• In photoshop, it is a file type that supports

  • clipping paths

  • duotone/tritone and quadtones

  • spot channels

• the EPS format preserves graphic elements you can create with Adobe Illustrator, which means that EPS files can be reopened and edited as Illustrator files

• If your artwork contains multiple artboards, they are preserved when you save to EPS format

jpeg- Joint Photographic Export Group

developed for exchanging information via the internet. Not suitable for printing

dcs- Desktop Color Separated Files

separates data into files for preview image and for each color channel

pdf-Portable Document Format

allows user to view and print independent of program that created it (Adobe Acrobat Reader)

Trapping

- process where colors are set to slightly overlap each other so white gaps do not appear

Choke

Technique of slightly reducing the size of the image to create a hairline trap or to outline.

Spread

Technique of slightly enlarging the size of an image to create a hairline trap or to outline.

Surprinting

colors do not trap, but overlap or print directly over each other. (overprinting on a background that causes it to be even darker)

• Dot Gain

• -phenomenon of halftone dots printing larger on paper than they are on films or plates, reducing detail and lowering contrast. Also called dot growth, dot spread and press gain.

  • in a film-to-plate workflow it is simply a characteristic of a process that uses pressure to transfer an into a substrate.

• Proof

• - a print made from negatives or plates to check for errors an flaws, predict results on press and record how a printing job is intended to appear when finished.

  • Soft- Digital files, such as PDF, viewed on screen.

  • Hard Proof- Physical, printed samples of the final project. They provide a tangible, more realistic view of colors, paper texture, ink, and finish.

Blueline

Prepress photographic proof made from stripped negatives where all colors show as blue images on white paper. “Blueline’ is a generic term for proofs made from avariety of materials having identical purposes and similar appearances.

Velox (white-print)

- a photographic reproduction of camera-ready art, made using a special photographic paper called Velox. Velox prints areused to make multiple copies of camera-ready art for distribution to various print advertising media. Velox prints have largely been replaced by the digital pdf.

Overlays

Color proof consisting of polyester sheets laid on top of each other with their image in register, as compared to integral proof. Each sheet represents the image to be printed in one color. Also called celluloid proof and layered proof.

Intergrals

Color proof of separations shown on one piece of proofing paper, as compared to an overlay proof. Also called composition proof, laminate proof, plastic proof and single-sheet proof.

Set off (off setting)

ink doesn't properly dry and transfers to the top of the sheet an black of another

Hickey

Hickey- Dust, dirt on rubber blanket or plate that prevents ink from printing, creating halos.

poor trapping

incorrect trap, to large, too small, wrong type, Makes boundary area/ overlap very noticeable.

Poor registration

gaps between colors or blurriness due to screens misregistered.
