proofing

Recently I was reading the 2009 PRIMIR/NPES “Sustainable Print in a Dynamic Global Market: What Going Green Means,” Executive Synopsis and it reminded me that back in February 2007 I tackled this topic in #68: Sustainable Green Printing. Among other conclusions the PRIMIR study agreed with my #68 post that sustainability is good business. So, knowing that a lot of my readers are looking for ways to make more money with less business these days here are a five tips to utilize color process control in a sustainability initiative that if properly run will result in a more profitable company.

1. Hard Copy Proofing – Fewer proofs in the trash equates to the use of less media, ink and electricity. Electricity you ask? Yes, even electricity. I am sure there are sustainability consultants that have quantified this part of the equation. Ongoing measurement and review of color quality will uncover workflow and mechanical problems before any or a large quantity of bad proofs are produced.

2. Virtual Proofs – Verifying and monitoring the display panel color fidelity insures that the device is used right up until it is no longer capable of displaying color accurately for proofing purposes. The device can then re-purposed limiting and delaying disposal of hazardous materials.

3. Plating – Gary Briney at Hennegan successfully uses ColorMetrix software to monitor and control printing plate production and saves thousands of dollars each year in raw materials and the electricity to produce “bad” plates. The PRIMIR report also makes reference to a company in Washington State saving $5,000 to $7,000 by recycling printing plates. So, even when a “bad” plate is made this company (and many I am sure) makes sure the metal and hazardous materials are properly recycled and disposed of.

4. Pressroom – With paper making up 26% of landfills the pressroom is an obvious area that any sustainability initiative must focus upon. Fortunately, the cost of paper, shorter cut-off presses and initiatives like the War On Waste begun in the 70′s have combined to make most pressrooms in this country fairly efficient from a paper waste point of view. Evaluation of color process control records will provide information necessary to continuously reduce makeready time and to identify when the press is not running at optimum levels and in its sweet spot.

5. Cross-media Control - Late last year I wrote about the fidelity of brand colors across the various mediums and substrates utilized in today’s POP displays. Imagine the environmental impact of a critical brand color not properly matching on multiple pieces of an in-store POP display. With proper color verification techniques the need to scrap and reproduce individual components of the entire display is virtually eliminated.

If you are not sure how to start a color verification and process control program to support your sustainability initiative take some time and review the achieves of JimRaffel.com.

#48: Make Proofs That Match Your Press

by JimRaffel on February 16, 2007

Since #45 in December we have been discussing resolutions to improve the quality of your proofs. In order to gain the full benefit of this installment one should have read and implemented the suggestions in #46 & #47.

Proceeding forward it does not matter if you are utilizing a methodology like GRACoL G7, or a more traditional color management approach. In either case you will include a target on each print job with the same color bar swatches that you output on the proof (#46). This will allow you to measure the press ok sheets and compare them to the proofs, thus building even a larger statistical database to call upon.

When utilizing software like our ColorMetrix and ProofPass.com products for process control and print certification purposes it does not matter if you are using a methodology like G7 or traditional color management. While there are some new formulas out there to run the collected data through the tried and true colorimetric data (L*a*b* and derivatives along with some version of Delta E), do a great job comparing two similar or dissimilar imaging systems.

Unlike density and dot gain values which must be used with pigment sets designed for 4/color process printing, L*a*b* values allow the comparison of an inkjet proof and an offset press sheet. This is possible because we are looking at the actual colors, not values derived from a formula which assumes a certain pigment set.

Not only will you be comparing the measurements of the proof to the press sheet, but you will be building a history of what is a “normal” print condition of each press and paper combination. Some refer to this as finding the “sweet spot” of the printing press.

Overall, as your volume of collected data grows you will be able to refine the system in small steps by reviewing the proofing and press information both independently and together. Using numeric results, charts, and graphs you will be able to see small differences in color that can be adjusted for over time. No system is stable over time, so continuous monitoring is a must in order to maintain stable color.
