Help with adding a curve to a profile...

Help with adding a curve to a profile...

2016-05-02 by john@...

Hi,


I have created profile for digital negatives using an all grey inkset. The profile installs and runs perfectly until I try to add a curve. I get the following error.


Curve specified “0;0 2;5 5;12 10;21 20;40 30;57 40;69 50;77 60;81 70;84 80;87 90;92 95;95 97;97 100;100” but no valid data found at /Library/Printers/QTR/bin/quadprofile line 41.


The profile is below. perhaps I am not using the right variable or syntax. In the past I had always used Curve_K and then Copy_Curve commands to apply the curve to all of the inks.


Here I am using the following aping what I have seen in other profiles.


GRAY_CURVE=“0;0 2;5 5;12 10;21 20;40 30;57 40;69 50;77 60;81 70;84 80;87 90;92 95;95 97;97 100;100”


Here is my complete profile:


#PRINTER=Quad3880

#12gm Speedball, 2gm Dunkel Brown, 2gm Violet

#CURVE_NAME= Carbon-800

#Based on an all gray ink set with 8 shades of gray.

DEFAULT_INK_LIMIT=50

N_OF_GRAY_PARTS=8

GRAY_INK_1=K

GRAY_VAL_1=100

Any help is appreciated.

The issue is the quotation marks. They are being converted to proper open and closed quotes. What text editor are you using to create the ink descriptor file?

I pasted what you have in and got the same error you did. then I changed the quote marks and it created the curves just fine.

Try this instead:

GRAY_CURVE="0;0 2;5 5;12 10;21 20;40 30;57 40;69 50;77 60;81 70;84 80;87 90;92 95;95 97;97 100;100"


Hope that helps,
