Here is a step-by-step instructional for printing the target we supply when you have InkjetMall produce a custom Piezography curve for use with QuadTone RIP.

We supply a special curve that is used as a “Master Curve” and a special 256 patch target that is printed. When you send the target back to InkjetMall for profiling, we email you the new curve. The instructions are different for matte and glossy media, whereas Glossy profiling gets an extra step.

To install the master, GO and/or custom curve, please drag and drop the curve into the following folder location:

(Windows) C\ProgramFiles\QuadToneRIP\QuadTone\Printer Model-K7

(Mac) /Applications/QuadToneRIP/Profiles/Printer Model-K7

NOTE: With Mac users, you must uninstall your Quad printer model then reinstall it using the install.command located in the same folder you placed the new curve in. This will show the new curve in QuadTone RIP.

Before printing the target image, print a nozzle check to make sure all nozzles are printing correctly. Make sure the target image is not changed in any way when saving or opening.
(Windows) Open the target image in QuadTone RIP and select the printer model specific Master Curve in the curve 1 list (select ‘none’ in the other curve pull down lists). Make NO changes to the Curve Bending or Advanced Adjustments sections (ink limit and gamma should remain at 0). Select Resolution: 2880dpi and Speed: Uni-directional. Print the target image at 100% scale.

(Mac) Make sure your Photoshop color settings gray working space is set to: Gray Gamma 2.2. Open the target image in Photoshop without making any adjustments to it. Print the target image at 100% scale, CS3: under Color Handling select “No Color Management” or CS4 (or higher) under Color Handling select “Printer Manages Color” and Intent: Realitive Colorimetric. Then push print to continue, in the QuadTone RIP window, select the printer specific Master Curve in the curve 1 pull down list (select ‘none’ in the other curve pull down lists), Make NO changes to the Curve Bending or Advanced Adjustments sections (ink limit and gamma should remain at 0). Select Resolution: 2880dpi and Speed: Uni-directional.

How to print the GO layer when using glossy media:

Print the target image with the K7-Master curve specific to your printer model, 2880dpi, uni-directional then dry the printed target either for a few hours air-drying or a few minutes of low blow drying.

Make a small (1×1” or smaller is fine) pure white (255, 255, 255) 300ppi image in Photoshop, feed the printed target sheet back into the printer and print the white square thru QTR by selecting the GO curve at 1440dpi and bi-directional speed to print an even layer of GO over the entire sheet (GO will print evenly over the maximum printable area, depending on the paper size you select).

Please write the printer model, ink, print settings and paper on the bottom of the printed target. Slip sheet (typing paper is fine) over the printed surface and sandwich the printed target between two pieces of cardboard (tape the edges so the print doesn’t move around inside) to protect it in shipping. The quality of the curve is dependent on the quality of the printed target.

Mail the printed target to the following address:

You can download the custom profiling package from here if you like. It includes a manual filled will all kinds of interesting information about calibration and displays. It also includes a linearization checker that you can use to see if your system might benefit from custom profiling. To use the Linearization Checker you’ll need both Microsoft Excel and a densitometer or spectrophotometer.  The download of course has all of the current Master Curves and the target.
