You can minimise this problem by

1.Using high quality paper ( coated )

2. Replacing old cartridges with new ones at the same time.

3. Not leaving the cartridge carriage empty without an ink cartridge installed for more than a few seconds

4. Replace empty cartridges as soon as they run out.

5. Run a print head clean when you change cartridges over

Again if there is a print head blockage, partial or total loss of one or more colours can occur. This can result in print outs that look dramatically different than the original file image.

Run a nozzle check to see if there is a blockage and then run a clean if needed.

Premium quality paper does not need as much ink to record the true image.

The crackle effect known as "Coalescence" can be caused by the ink output being to fast or to high for the paper being used. The ink is being jetted faster than the paper receiving layer can absorb.

Reduce the print speed. In your print settings choose the highest resolution possible and the finest drop size possible. Choose the highest quality media such as Glossy Film (not transparency film). Choose the best dither method such as error diffusion (for Epson use super microweave if it is available).

Some inks such as pigmented inks are not compatible with all types of paper.

The file may look good on screen but the print is different.

This can be caused by the monitor not being calibrated to the printer.

Or the file being only low resolution eg web images are generally 72 Dpi to get photo quality print outs you would prefer 300 Dpi images.

Correct Skin tone is lost, and detail in blacks and shaded areas are lost.

Also check the printer driver settings match the recommended paper settings.
