Sharpening and paper

Hi again.

I have used mainly luster and glossy paper. The output sharpening is made by Qimage Pro and I have been happy with the result.
Now I have started to use matte and fine art paper as well.

A very simple but basic question: Should I increase the sharpening in Qimage? (all other variables fixed). Matte paper needs more sharpening than glossy, and does Qimage take this into account or should I do it myself?

I don't think Qimage takes into account the paper type; smart print sharpening works from image and print size data.
You probably know that the idea with Qimage print sharpening is to get a print that matches the screen image wrt sharpness appearance so it's up to you to set it to your taste. Usually, once set it can be left. I regularly use matte paper and have occasionally used fine art paper and never found I needed to increase the level of print sharpening so am not convinced that "matte paper needs more sharpening than glossy".

Thx for the fast reply (as usual, I really appreciate it).

Ok, I will make some tests with different sharpen values.

But I am quite convinced that matte paper needs more sharpening than glossy. And some experts seem to share this:

"Regardless, the necessary amount of sharpening will still likely depend on the image content, type of paper, printer type and the look you want to achieve. For example, matte/canvas papers often require more aggressive sharpening than glossy paper". http://www.cambridgeincolour.com/tutorials/image-sharpening.htm

and

"If you're printing to an Epson ink jet, you'll need more sharpening for matte media than for glossy media." http://www.pixelgenius.com/tips/schewe-sharpening.pdf

Yes and smart sharpening takes care of some of these factors and makes it very easy to adjust when required so that you do have to modify the image for every printer, paper type, print size variation Cool

Q Help says:
Final Print Sharpening - Qimage offers the ability to apply different levels of unsharp mask to the final print. This unsharp mask is applied after all interpolation has been performed (after your print has been resampled to the DPI of your printer). Since this setting affects the sharpness of your prints, a setting should be used that makes your final prints match what is displayed on your monitor with respect to sharpness. The type of printer used and the print driver version can affect apparent sharpness of prints. It is best to leave this setting at the default slider position unless you prefer softer or sharper printed images.

You can't beat trying it for yourself Wink

Have fun!
