Unit
- Print versus digital: Print design uses CMYK color mode and requires 300 DPI resolution for sharp output. Digital design employs RGB and 72 PPI for screens. Layout differences include bleeds (extra 0.125 inch) and safety margins for print, while digital uses fixed pixel dimensions.
- Color accuracy: Print relies on subtractive color mixing with cyan, magenta, yellow, and black inks. Digital uses additive RGB. Screen colors appear active but may not reproduce faithfully in print without proofing. Calibration ensures consistency.
- Resolution and detail: Print demands high-resolution images to avoid pixelation. At 300 DPI, a 1-inch square contains 90,000 dots. Digital screens display lower resolution comfortably. Upscaling low-res images for print leads to blurry results.
- Typography and legibility: Print allows fine kerning and leading adjustments for readability. Serif fonts are often preferred for body text. On screens, sans-serif fonts are common due to lower pixel density. Hyphenation and widows matter in print.
- Design constraints: Print has fixed dimensions and requires consideration of paper grain, binding, and finishing. Digital designs can be responsive and interactive. Print elements like registration marks and crop marks are unnecessary in digital.
- Proofing and testing: Print requires physical proofing (e.g., bluelines, digital proofs) to check color and alignment. Digital allows instant previewing on devices. Soft proofing simulates print output but cannot guarantee match.
- Cost implications: Print errors waste materials and time. Rework requires new print runs. Digital changes are cheap and fast. Designers must verify file specifications before sending to print.
- Audience experience: Print offers tactile engagement through paper texture and weight. Digital provides interactivity and hyperlinks. Both media require audience-specific design strategies.
- File formats and preparation: Print files are typically saved as PDF/X or TIFF with embedded fonts and high-res images. Digital uses JPEG, PNG, or GIF with sRGB color. Print-ready PDFs require flattening transparency and outlining fonts to prevent substitution issues at the printer.
- Binding and finishing options: Print designs account for saddle stitching, perfect binding, or spiral coil. Folding, die cutting, and foil stamping add production steps. Digital layouts never need spine width calculations or grain direction considerations for folding without cracking.
- Environmental and sustainability factors: Print uses paper, ink, and energy. Designers can choose recycled stock, soy based inks, or reduce page count. Digital has server and device energy costs. Both media have ecological footprints that influence client decisions and design briefs.
Design Principle
Principle: Resolution Matching for Output Mediums
Definition: Selecting image resolution based on the final output device. Print requires 300 DPI at final size, while digital screens need only 72 PPI. Using incorrect resolution degrades quality or increases file size unnecessarily.
Application: Before placing images in a print layout, use software to check the effective DPI. For a 4x6 inch photo, the image should be at least 1200x1800 pixels. Downsample images for digital use to keep files manageable. Always work with high-resolution originals.
