印刷清晰度检查使用指南Print Resolution Checker: guide

读取图片像素或手动输入尺寸,计算有效 PPI、所需像素与可印尺寸,预估裁切和留白。Read image pixels or enter dimensions to calculate effective PPI, required pixels, printable size, cropping and whitespace.

  1. 选择 PNG、JPEG、WebP 图片,或手动输入像素宽高;输入印刷尺寸与目标 PPI。Choose a PNG, JPEG or WebP image, or enter pixel dimensions. Set the print dimensions and target PPI.
  2. 选择铺满裁切或完整留白,查看有效分辨率、可印尺寸并复制检查结果。Choose crop-to-fill or fit-with-whitespace, inspect the effective resolution and copy the results.

达到目标 PPI 就一定清晰吗?Does meeting the target PPI guarantee a sharp print?

不一定。这里只检查像素密度,不检测失焦、压缩损伤、颜色或细小文字。300 PPI 为常用参考值,以印厂要求为准;PPI 不等于打印机 DPI,修改 DPI 标签不会增加真实细节。图片在本地读取,限 30 MB、1600 万像素;预览不等于屏幕上的真实打印尺寸。No. This checks pixel density, not focus, compression damage, color or small text. 300 PPI is a common reference; follow your printer requirements. PPI is not printer DPI, and changing a DPI tag adds no real detail. Images stay local, up to 30 MB and 16 megapixels. The preview is not actual print size on screen.
