We commit ourselves providing you an ICC profile made to measure for your printer. The success of this operation is subjected to a scrupulous respect of the instructions which you will receive with the ICC Target to print.
Good profiles which are used wrongly will never lead to good prints.To familiarize you with Color Management and use of ICC profiles, you can find many sites and forums covering these subjects.
We could not be held for persons in charge :
of a bad impression of ICC Target,
of a degradation of it during its shipment,
of a persistent difference between your prints and display of your screen in spite of the use of a profile.
ICC profiles should be used with a correctly calibrated monitor. Many methods and several free software (Adobe Gamma, WiziWYG…) make it possible by obtaining convincing results.
