Color Analysis and Substrates Overview

Substrates

• Substrates have properties like caliper (thickness), grain, and other characteristics.
• Substrate selection considers basis weight, formats, and more.
• Manufacturing methods vary (e.g., papermaking, film making).

Color Analysis

• Color analysis involves measurement and differentiation.
• Spectral reflectance is a key aspect.
• Density and Delta E (color difference) are used in assessments.
• Color spaces (Lab, CMYK, RGB) relate colors numerically.
• Hue, chroma, and tone value (e.g., MD, SCTV) are important color attributes.
• Human perception influences color analysis (e.g., lighting, background).
• UV light can affect substrates, influencing color.

Color Reproduction

• Color profiles are used to manage color reproduction.
• Colors may appear differently depending on viewing conditions.
• Multiple variables affect color reproduction accuracy.
• Tone value (dot gain compensation) is crucial in color matching.

Proofing

• Proofing uses specialized equipment and software (e.g., spectrophotometers).
• Proofing aims for accurate and original-like color representations.
• It helps predict print outcomes from the press.
• Proofing systems receive press characteristics to get accurate color predictions.

Ink

• Various ink types exist.
• Different printing processes may require specific inks.
• Ink production costs can be significant, especially for large-scale projects.
• Ink properties (e.g., pH, viscosity) impact print quality.
• Additives affect inks' properties and performance.

Measurement Instruments

• Measurement tools are used in color analysis and print processes.

Practical Application

• Color spaces (e.g., Lab) are used in various downstream processes.
• Files must be prepared correctly for printer input.
• Color evaluation in printing uses percentages and factors.
• Print color consistency relies on accurate evaluation and standard procedures.
• Accurate press evaluation is important for quality reproduction.
• Print projects rely on correct color selection and matching.
• Color and print consistency is critical to maintaining branding.
• Implementing these processes is vital for accurate predictions in print projects.
• International Color Association (ICA) standards (e.g., ICA4).
