Charts designed for screen viewing often disappoint when printed. Colors shift, text shrinks, and fine gridlines disappear. This guide covers the three settings that matter most for print-ready exports.
Set DPI Before Exporting
Screen displays use 72-96 DPI. Print requires 150-300 DPI. Export your chart at 300 DPI for brochures and reports, 150 DPI for internal documents, and 96 DPI for web embedding. Changing DPI after export by upscaling a low-res PNG introduces blur.
Use CMYK for Professional Printing
Screens display in RGB. Commercial printers use CMYK. If your chart will appear in a professionally printed report, export as PDF with CMYK color space. For office printers and internal use, RGB PNG is fine.
Choose the Right File Format
PNG works for most chart exports with clean edges and text. SVG is better when you need infinite scalability. PDF is the standard for print-ready documents. Avoid JPEG for charts with text or sharp edges — the compression artifacts are visible.
Quick Checklist
- Screen only? → PNG at 96 DPI, RGB
- Internal PDF? → PNG at 150 DPI, RGB
- Professional print? → PDF at 300 DPI, CMYK
- Need to resize later? → SVG
DataVizForge handles all three export formats with DPI control built in. Set your target before exporting, and the chart renders at the correct resolution. Feedback: sapsap@qq.com.
