Corel Print House

Corel Print House is a discontinued desktop publishing application.

It has a native .cph format, which is based on Microsoft Compound File format. CPH appears to be similar to, and possibly identical to, Corel Print Office's CPO format.

Released in 1995, there are editions named Corel Print House Magic, and Corel Print House 2000. Some editions include Corel Photo House as a component. The last version was Print House 6

Corel Custom Photo was a set of CD-ROM's released in 1999 which included Corel Photo House 5 and Corel Project Designer 5, which seems to be a rebranded version of Corel Print House. File extension is .CPD, but format is identical to Print House formats.

File Identification
From Corel Print Office ReadMe:

Q - Can I open older versions of Print House in Print Office.

A - Yes but the file extension must be changed first. Print House files have the extension CPH and Print Office files have the extension CPO. In order for Print Office to recognize the older file type, the extension must be changed to CPO.
