Agenda Defining Color RGB vs CYMK Types of Inks Process Colors Pantone Spot Colors Coatings

UNDERSTANDING COLOR EMITTED LIGHT COLOR (RGB) Red Green Blue Computer Screens / Television What Designers…..Design with….

UNDERSTANDING COLOR REFLECTIVE LIGHT COLOR Used to print images Transparent Inks Light travels through ink and bounces off paper behind back through ink to eyes.

FOUR COLOR PROCESS Reproducing Continuous Tone Photography Cyan Yellow Magenta BlacK

Ink Categories Standard Inks Web Offset – Non Heatset Web Offset – Heatset Quickset Inks Sheet-fed Inks Soybean Inks Water based Inks – Flexo and Gravure Laser Inks UV Inks

Ink Categories Specialty Inks Non-porous Inks Metallic Inks Magnetic Inks – MICR for checks Fluorescent Inks Edible Inks Scratch and sniff Inks Security Inks – Document Security

Types of Ink Transparent Lithography Light reflected from paper thru ink Opaque Screenprinting Light reflects off surface of ink Toners Digital Print Engines

Ink Problems Setoff (Offsetting)

Ink Problems Ink Adhesion Mottling – uneven appearance Fill-in – muddy look in halftones/screens

Printing Four Color Process Start with scanned image or digital image Place image into printed layout RIP the document Create dot map of each process color Image dot map to printing plates One to One relationship
