ACE Exporting for Web and Print 3 — Questions and Answers
Question 1: You need to export a logo on a transparent background for a website. Which format preserves full alpha channel transparency?
- JPEG
- GIF
- PNG-24 (Correct answer)
- BMP
Correct answer: PNG-24
PNG-24 supports full 8-bit alpha channel transparency, unlike GIF which only supports binary (on/off) transparency.
Question 2: What is 'pixel doubling' (2x assets) used for in web export workflows?
- Increasing JPEG quality artificially
- Providing high-resolution images for Retina/HiDPI displays (Correct answer)
- Reducing file size by halving dimensions
- Creating animated sprite sheets
Correct answer: Providing high-resolution images for Retina/HiDPI displays
2x assets are double the CSS pixel dimensions so that Retina and HiDPI screens render images sharply without upscaling.
Question 3: Which Photoshop feature lets you export individual layers or layer groups as separate image files automatically?
- Flatten Image then Export
- File > Export > Export Layers to Files (Correct answer)
- Layer Comps to Files
- Image Processor with layer selection
Correct answer: File > Export > Export Layers to Files
File > Export > Export Layers to Files iterates through each layer or layer group and saves them as individual image files.
Question 4: A designer sets canvas size to 8.5×11 inches at 300 ppi for a print document. What pixel dimension does this produce?
- 612 × 792 px
- 2175 × 2775 px
- 2550 × 3300 px (Correct answer)
- 3400 × 4400 px
Correct answer: 2550 × 3300 px
8.5 × 300 = 2550 px and 11 × 300 = 3300 px, so the canvas is 2550×3300 pixels at 300 ppi.
Question 5: When using Photoshop's 'Package' feature (File > Package), what does it collect?
- All open Photoshop documents into one PDF
- The PSD and all linked smart object files into a single folder (Correct answer)
- All fonts used in the document
- Export presets and color profiles
Correct answer: The PSD and all linked smart object files into a single folder
File > Package copies the PSD and all externally linked Smart Object files into one folder, ensuring handoff completeness.
Question 6: Which blending mode interaction requires 'Flatten Image' before exporting to JPEG to avoid unexpected color changes?
- Normal mode layers
- Layers using blend modes like Multiply or Screen (Correct answer)
- Locked background layers
- Adjustment layers set to Pass Through
Correct answer: Layers using blend modes like Multiply or Screen
JPEG does not support layers or blend modes; flattening merges blended composites into final pixel values so the export matches the on-screen appearance.
Question 7: What is the role of 'rendering intent' when converting a wide-gamut image to sRGB for web export?
- It determines how pixels are resampled during resize
- It defines how out-of-gamut colors are mapped into the smaller color space (Correct answer)
- It sets the bit depth of the output file
- It controls JPEG compression algorithm
Correct answer: It defines how out-of-gamut colors are mapped into the smaller color space
Rendering intent (Perceptual, Relative Colorimetric, etc.) determines the strategy used to translate colors that fall outside the target color space.
