In the further part of this page we have added a list of programs that should open your ATF file. It is enough you choose a proper application for your operating system, download and install it.


An ATF file is a so-called Adobe Transfer Function file, ie a settings file for the transfer function of the image processing software Photoshop. In the German version this file is called a print characteristic. An ATF file stores information that is used for adjustments and corrections of possible image changes when transferring images to eg different print materials such as film.

When using different printing presses, printing materials or printing inks can lead to a dot gain. This can lead to a difference between the original image and the print.

The print characteristic is used to add or subtract pixels or dots depending on the setting. To create an ATF file yourself, select 'Output' in the 'Print' dialog of Photoshop and then the 'Print characteristic' button. Once you have made the desired setting, you can save it in an ATF file via 'save'. In this dialog also ATF files can be loaded.

It should be noted that when transferring multiple images for each image you have to create an ATF file separately.

How to open a ATF file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the ATF 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 ATF 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 ATF files. At this point we are looking for disk space where the application was installed in and we can link it with a ATF file. Since then, our operating system will use the selected program to support all ATF files.

Other issues

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

- verify that the ATF 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 ATF 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.
