Sharpening question

Hi Andy,

does Qimage factor in a different or size appropriate amount of sharpening if you do a 8x10 print and then do a 24 x 30 print and leave the sharpening slider in Qimage at the default of 5? In other words, if you liked the amount of sharpening Qimage does with the slider at the default(5), will a comparable amount of sharpening be done for a 24 x 30 print of the same image of do you need to increase the amount of Qimage sharpening the larger you go in print size to get a comparable amount of sharpening.

The simple answer is YES!
The full name is Smart Print Sharpening - smart because it takes acount of print size ans other factors automatically.

This is what the Help/final print sharpening:

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. To make images look sharper, slide the slider to the right. To make images appear softer in print, slide the slider to the left. The following are notes that apply to the two different types of final sharpening available in Qimage:

Smart sharpening: Smart sharpening uses information such as resolution of the original image, the printer driver PPI, and the final print size to set the parameters of the sharpening algorithm to produce consistent, vibrant sharpening in every print. Smart Sharpening is the preferred setting.

Note what is says about setting the level so the print matches what you see on screen wrt to sharpness
