5.11 Print

This menu contains items which should be useful when preparing an image for printing.

Sharpen_for_print
Sharpens an image for print output. Open the row to adjust the target DPI. Tuned for inkjet printers.

Morph_for_print
Use this to make colour adjustments for print to match under target conditions. You can straighten the grey scale and adjust lightness and cast.

Tone_for_print
Adjust the reproduction tone curve in LAB. Most useful for offset work, especially from transparencies.

ICC_import etc.
Use these to transform from device space to profile connection space (LAB float) and back.

You need to be careful about colour temperature issues: all printers work with D50, and nip is all D65. For example, to import a D65 LAB image from device-space use Print=>D50Lab_to_D50XYZ to get an XYZ image with a D50 whitepoint (it'll look orange, that's OK). Use Colour=>Colour_temperature=>D50XYZ_to_D65XYZ to approximate D65 from the D50 image. Use Colour=>XYZ_top=>Lab to make a D65 LAB image.

All printers also work with relative colorimetry, and nip is generally absolute. Use ICC_ac2rc to scale an absolute colorimetric image by a media white point.

Drop_shadow
Use this to add a cute drop shadow to images. Handy for web pages.
