GRACoL 7 Questionnaire

1. Do you agree with the technique of using gray balance and the Neutral Print Density Curves to help match images in prepress and fine tune density adjustments while running the press?

Yes
No

2. Do you agree with the unambiguous definition of gray balance used by GRACoL?

Yes it should have a definite Lab value
No, gray balance should be based on color of black ink
No, gray balance should be based on paper color
No, because

3. Were you happy with the profile overall? Do you think it provides a good match to your press?

Yes
No

4. Were you satisfied with the relationship of the black curve with the 3-tone gray curve at the midtones?

Yes, Black should be lighter than the 3-tone curve like SWOP TR 001
No Black should be equal to 3-tone curve
No Black should be darker than 3-tone curve

5. Do you think this work would be a good basis for an international commercial printing specification?

No
Yes
Don't care

6. Have you calibrated a press according to the G7 method?

Yes
No

7. If Yes, did the resulting tone curve and gray balance compare favorably to your previous press condition?

Yes
No

8. Are you still using the G7 calibration?

Yes
No
N/A

9. Have you profiled a press that was calibrated to the G7 method and compared it (in Photoshop or by comparing to a G7 beta digital proof) to the GRACoL 7 characterization data published on April 10?

Yes
No

10. If Yes, do you feel your press came close to matching the data?

Yes
No

11. If No, can you describe the differences and/or send us your profile or measured data? Short description of differences
