Have you encountered a problem with a CH file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a CH file here. In the further part of this page we have added a list of programs that should open your CH file. It is enough you choose a proper application for your operating system, download and install it.


A CH file is a so-called Scitex Continuous Tone file, ie a graphics file of the Scitex Workstation. The image data of a CH file is in CMYK, RGB or grayscale format and is mostly used for very large files to maintain full quality.

This format is often used on high-resolution Scitex scanners and is used in high-end prepress. In addition to the file extension CH, such files are also provided with the suffix ct, sct or sc.

Changing the extension may be useful if the file can not be opened directly.

How to open a CH file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the CH file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a CH file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support CH files. At this point we are looking for disk space where the application was installed in and we can link it with a CH file. Since then, our operating system will use the selected program to support all CH files.

Other issues

Despite the described problem with CH there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the CH file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the CH file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
