So you say adobe would fix it if ACPU would be commercial software? I think it should be part of photoshop that is commercial software.
I don't disagree, that's just not going to happen. As I said, we had literally years of issues between printer manufactures drivers, Apple and Adobe and Adobe decided one '
fix' was to disable this print path.
You do know Photoshop allows to work with non-color-managed images, allows to untag profiles etc.
Not really. You can't turn off color management in Photoshop. An untagged document is still color managed in terms of an assumed color space (whatever you have set in it's Color Settings dialog for working space) along with the display profile. And like that approach, so is the print path. You can feed it untagged data but it is still going to assume some color space for the RGB or CMYK numbers and deal with them as such.
Even with GWGill's suggestion, (that color management was conducted outside Photoshop), that data
has to have an embedded profile OR Photoshop assumes a color space for the numbers that probably isn't correct. So again, why would anyone feed Photoshop an untagged document for output? It isn't designed for this workflow and it's kind of a pointless workflow too. Untagged RGB and CMYK is mystery meat. For color targets, we don't care how the
image appears. For actual images, we do and that's why Photoshop forces color management upon it's data.
