ACE Output for Print and Web 3 — Questions and Answers
Question 1: Which file format best preserves transparency when saving web graphics that require smooth edges on non-rectangular shapes?
- JPEG
- GIF
- PNG-24 (Correct answer)
- BMP
Correct answer: PNG-24
PNG-24 supports full 8-bit alpha transparency, allowing smooth anti-aliased edges on any background.
Question 2: A client requires a Photoshop file submitted with all spot colors intact for a two-color print job. What should you do?
- Convert to CMYK and delete unused channels
- Keep the file in RGB and note the spot colors in a comment
- Use Spot Color channels in Multichannel mode or alongside CMYK (Correct answer)
- Merge all channels before saving
Correct answer: Use Spot Color channels in Multichannel mode or alongside CMYK
Spot Color channels preserve specific Pantone or custom ink separations needed for two-color or special ink print jobs.
Question 3: What is the recommended image resolution for standard inkjet photo printing at a typical viewing distance?
- 72 ppi
- 150 ppi
- 240-300 ppi (Correct answer)
- 600 ppi
Correct answer: 240-300 ppi
240–300 ppi provides sufficient detail for inkjet photo printing without unnecessarily large file sizes.
Question 4: In the Save for Web dialog, which setting controls the number of colors in a GIF export?
- Quality slider
- Colors field in the Color Table panel (Correct answer)
- Dither percentage
- Lossy slider
Correct answer: Colors field in the Color Table panel
The Colors field in the Color Table panel lets you set the maximum number of colors (2–256) in the GIF palette.
Question 5: When preparing a document for web display, which color mode should the Photoshop file be set to?
- CMYK
- Lab Color
- RGB (Correct answer)
- Grayscale with spot channels
Correct answer: RGB
Monitors display color in RGB, so web images should be in RGB mode and ideally use the sRGB color profile.
Question 6: What does 'Total Ink Coverage' or 'Total Ink Limit' mean in a print workflow?
- The maximum DPI the printer can produce
- The combined percentage of CMYK ink that can be applied to any single point on press (Correct answer)
- The number of spot colors allowed per job
- The thickness of the print substrate
Correct answer: The combined percentage of CMYK ink that can be applied to any single point on press
Total Ink Limit caps the sum of CMYK ink percentages at one point to prevent oversaturation, smearing, or drying problems on press.
Question 7: Which Photoshop export option is best for delivering a high-resolution image to a commercial printer that uses a PDF workflow?
- File > Export > Export As PNG
- File > Save As > Photoshop PDF with Press Quality preset (Correct answer)
- File > Export > Save for Web as JPEG
- File > Export > Export As TIFF with LZW compression
Correct answer: File > Save As > Photoshop PDF with Press Quality preset
Saving as Photoshop PDF with the Press Quality preset embeds color profiles and maintains full image data for professional printing.
