What would be the best direction to go with the following press paper and proofing paper? Use uv cut filter or not. Proofing paper L*a*b* values measured without UV cut. No UV filter. L= 96.38 a= 1.83 b= -8.02 Press paper L*a*b* values measured without UV cut. No UV filter. L= 93.80 a= 1.76 b= -8.20 Both the proofing paper and the press paper appear to have optical brighteners as seen under a black light. I'm planning on doing a G7 calibration. Creating a profile of the press after G7 calibration and creating a proof to match the press using the press profile. With both papers having optical brighteners, what would be the purpose of using a UV cut filter? -- Steve Miller Color Management Specialist "Quality Begins Here" BIC Advertising & Promotional Products 1000 3rd Ave. SW Sleepy Eye, MN 56085 Tel.: (1) 507 794 8203 E-mail: slmiller@norwood.com www.norwood.com / www.bicgraphic.com CONFIDENTIALITY NOTICE This electronic message is confidential and may contain legally privileged information intended only for the use of the individual or company named above.

I'm looking for a spectrophotometer that can measure non flat surfaces. Small round cylinders about the size of a pencil. Is there anything on the market that is capable of this?

Hi Steve, The ab* values are very close in my opinion. If you can remeasure with UVexcluded and the ab* values remain close (< ab* 0.5) then the papers have similar brightener loads and should look similar to the eye under a variety of lighting conditions to both your eye and your instruments. I would think you could go about your job either way under the circumstances. That being said I do not know of anyone using UVexcluded data for offset press to hard copy proof tasks because many of us enjoy comparing our results to standard print specifications such as Fogra47. The exception to this trend is in softproofing where a UVexcluded version of the press profile makes sense because it prevents the substrate from looking too blue on screen.
