Thank you Mike - I'll take a look at your suggestion - sounds right to me.

Later - yes! that will work perfectly. Thank you!

I have several different custom print sizes that I have added over the years. Some are for one printer, while others are for a dye-sub printer for which there are many different sized prints for different products, etc. Right now I have 58 print sizes and need to add several more. Is there any way to divide print sizes into separate files in order to make them more manageable? Say one for each printer?

Thanks Mike - that's good suggestion about using printer setups. I'll try that.

As for the flt files not being user-editable, I assume you actually mean they are not meant to be. I have made my own by modifying some of the parameters in a text editor, and saving them into the filters directory under a new name, and used them successfully for several years now. But I sure would like to know the ins-and-outs of the flt file structure.

Thank you Fred, but that didn't answer my question: Is there a template or other document that I can go to to see what the various line entries in *.flt files are controlling? That is the main question for me. I would like to understand what all the entries are controlling.

One related question - how do you enter a comment in the *.flt files? Would they be preceded with a "#" or "/" or some other character?

I am using a global filter to fine-tune my custom printer profile, and would want it applied to all prints on that particular printer. I don't do any editing or filtering on individual images, other than basic crops in QI, and I expect all files to be printed as visualized in my post-processing workflow, which is basically either via LightRoom, PhotoShop or CorelPainter. It would be a lot easier if I knew what the various numbers mean.

Is there a template or other document that I can go to to see what the various line entries in *.flt files are controlling? Is the format different for the pre-defined filters and the .flt files generated in the file directory with the image(s)? They seem to be slightly different. Can an .flt file generated for an image be used as a global filter?

Thanks Mike - how does your "Overdrive" setting of 1440ppi come into play? Is that no better than the native 720?

I am using an Epson Stylus Photo R2400 printer. On some types paper, you can set their quality setting to "Photo RPM" which is 5700x1440 dpi. In order to utilize this high resolution should I set the Qi Print Resolution setting to "OFF", since the highest resolution offered is 1440 ppi?
