What are CPH files and how to open them

What is a CPH file?

A .CPH file is a Corel PrintHouse Image file.

Corel PrintHouse Image files are documents produced by the home publishing software Corel Print House. They store full print layout projects including pages, text, vector outlines, fills, graphical pages, and possibly thumbnails. The format is used when designing greeting cards, calendars, banners and similar multi-element, print-ready documents.

These image files are created and saved only by Corel Print House. Once a project is completed, the user generally exports or saves it into more widely supported formats like JPEG, BMP, WMF, TIFF, GIF or other vector/presentation exchange formats so that printers or other graphics programs can use them.

The file structure of these images is based on Microsoft's Compound File Binary Format (also called OLE structured storage). They begin with the signature bytes 0xD0CF11E0A1B11AE100 at the very start of the file. Internally they include named storage entries such as ROOT ENTRY, THUMBNAIL, CONTENTS, WGRAPHICPAGE, WOUTLINEHANDLE and several others which hold different streams like outlines, fills, graphic page data, handles and geometry.
