Quizzes
i.Knowledge
Knowledge questions test whether the learner understands PNG terminology and core rules without relying on software-specific labels.
Question Expected answer Is PNG raster or vector? Raster Is PNG compression lossless? Yes Can PNG store transparency? Yes, depending on color type and transparency information Does changing PPI metadata create new detail? No Does PNG define a standard CMYK image color type? No Can PNG contain editable cut paths or embroidery stitches? No What determines production compatibility? The complete file, method, software, machine, material, and product workflow ii.Identification
Identification questions ask learners to recognize visible or technical properties and route the file to the correct next check.
Prompt Learner identifies A checkerboard behind isolated artwork A viewer convention representing transparent areas, not necessarily printed pixels A 1200 px image requested at 12 inches 100 effective pixels per inch A sticker image with no contour path Raster print artwork with missing cutting geometry if contour cutting is required A white rectangle behind a logo An opaque background, not transparency A file that looks sharp at small size but soft when enlarged Fixed raster resolution A PNG supplied for embroidery production A visual source that still requires digitized stitch data iii.Scenario
Scenario questions test judgment when more than one fact must be considered.
Scenario 1
A creator has a 3000 × 3000 px PNG for a 10-inch square print. Calculate the effective resolution and decide whether to compare it with the maker's requirement.
Scenario 2
A transparent logo shows a dark edge on a white mug mockup. Identify the alpha edge as the first inspection target before changing machine settings.
Scenario 3
A maker receives a PNG for a print-and-cut sticker. Determine whether a separate vector contour or an approved contour-generation step is required.
Scenario 4
The same file prints differently on two garment colors. Explain the role of garment color, underbase, material, profile, and proofing.
Scenario 5
A valid PNG is submitted for CNC routing. Explain why a toolpath-capable geometric file is still required.
iv.Troubleshooting
Troubleshooting questions evaluate whether learners isolate the source of a failure instead of changing several variables at once.
Symptom Best first check Image is blurry at final size Actual pixel dimensions and effective resolution Artwork imports at the wrong size Software units, metadata interpretation, and automatic scaling Only one machine produces banding That machine's diagnostic and maintenance state One material lot transfers poorly Material specification, lot, preparation, and storage Every unit is mirrored incorrectly Where mirroring was applied in the workflow A correction appears successful Produce and inspect a controlled verification result before resuming
