Top Quick Tips for Flattening Transparencies with pdfAssistant
1. Choose the Right Quality Setting
The Tip: Match the flattening quality to your final output.
How to Do It:
- Low: For web use or basic office printing.
- Medium: Ideal for most desktop color printers.
- High: Best for commercial print production where accuracy matters.
2. Flatten Before Sending to Print
The Tip: Avoid surprises at the print shop.
How to Do It: Flattening ensures consistent results across devices—even legacy or budget printers that don’t handle transparency well.
3. Combine with Other Print-Optimization Tools
The Tip: Flattening is even more powerful as part of a prepress workflow.
How to Do It: Pair with other pdfAssistant capabilities for print-perfect PDFs:
- Convert PDF Colors: Switch RGB to CMYK for accurate print color.
- Convert to PDF/X: Meet industry print standards.
- Rasterize PDF: Create fully flattened pages for older RIPs.
4. Review Your Document After Flattening
The Tip: Some visual shifts can occur.
How to Do It: Check areas with transparency effects like drop shadows, overlapping images, or vector artwork to ensure colors and shapes remain accurate.
5. Save an Editable Version First
The Tip: Flattening is permanent.
How to Do It: Keep an unflattened copy in case you need to revise layered artwork later.
6. Use Flattening for Maximum Compatibility
The Tip: Flattened PDFs work reliably everywhere.
How to Do It: Use transparency flattening when submitting files to older printers, government portals, or archival systems.
7. Test with a Single Page First
The Tip: Preview before processing large documents.
How to Do It: Flatten one test page to confirm color and effects render correctly before flattening the full file.
8. Check with Your Print Provider
The Tip: Requirements vary across printers.
How to Do It: Ask whether they recommend flattened PDFs, specific quality settings, or PDF/X standards.
