AVA Profiler is an application used to build CMYK profiles. It can be located in the following location on your Mac®: Applications / AVA 5.nn / AVA Utilities / Profiling
CMYK profiles can be useful for a number of workflows. For example, separation artists may use the Separate > With Profile function when separating CMYK images, or those who use the CMYK Colour Picker will have to have a CMYK profile set for the picker to work. If this CMYK profile is created directly from your production inks, it will provide separation artists with accurate CMYK separations, and those using the CMYK Colour Picker with accurate, true-to-production colours as they colour their designs.
How to use AVA Profiler
Before you can use AVA Profiler, you need to have some ECI 2002 target measurements. For customers undertaking a Production Colour Management project with us, we will have supplied a target for you to print in production and would read the measurements for you into PrinterCal. Other software applications provide ECI targets and depending on the file format of the measurements file, may be used in the AVA Profiler.
- Launch the AVA Profiler app from the following location: Applications / AVA 5.nn / AVA Utilities / Profiling
- Go to File Menu > Open and locate your ECI 2002 measurements file.
- In the General tab, select D65 and 2° from the corresponding drop down menus. This is the standard lighting conditions AVA recommend for accurate colour matching.
- In the Simulation tab, leave the profile space as Lab, but change the Profile Model to ‘More Accurate.’
- Move the Smoothing to ‘Close to measurements.
- Saturation density can stay at 3.20. If you require more accuracy, you could locate the black chip from the ECI 2002 measurements and check it’s density using the Dot Area function of Coloursys to find out the true density. However, 3.20 is a good average.
- Click on the Separation tab. The following pane will open:
- Click in the Max Ink Ink Coverage field.
- Press the Tab key on your keyboard.
- AVA Profiler will begin to build your profile.
- If the curves do not quite touch the top right hand corner of the window, you could increase the Max Ink Coverage to 400%.
