Optimize Without Losing Quality

While optimizing artwork reduces file size and upload time, excessive compression can degrade image and text clarity. This affects proofing accuracy, especially for pixel-based comparisons, barcodes, and small print details.

Best practices

• Apply lossless compression for text, barcodes, and vector graphics to retain sharp edges.
• Maintain a minimum resolution of 300 DPI for print-ready images to ensure visual fidelity.
• Avoid high JPEG compression, which can blur fine details and distort pixel comparisons.
• Always review optimized PDFs by zooming in to verify no visible quality loss.

Why it matters for proofing?

Low-quality or overly compressed artwork can cause the proofing tool to misinterpret fine details, resulting in inaccurate deviation reports or missed defects. Maintaining optimal quality ensures precise visual and pixel comparisons across revisions.
