How to stop printing bad proofs

Money jar depicting savings on proofsThis was originally posted on JimRaffel.com on Jan. 9, 2007. It has been revised for this blog. You can view the original here.

At the close of 2006, ColorMetrix CEO Jim Raffel presented three proofing New Year’s resolutions, which he promised to expand upon in 2007. Resolution #1 stated that printers should “increase productivity by decreasing time wasted to re-print bad proofs.” It sounds simple; and it can be.

First, printers must start measuring the color bar they output on every proof with process control software, such as ColorMetrix’s ProofPass. Implementation of color verification solutions allows for analysis of the historical data using a built-in trending module or exported data into an application such as Microsoft Excel.

By doing this over a period of time (we suggest a month), printers will be able to determine the normal variation of their proofing process. Not every proofing system has the same normal variation; nor do any two similar proofing systems have identical variation. Once the normal variation is known, reasonable and achievable tolerance levels for the proofing system can be built.

If the tolerance levels from the previous step of this process are not what is wanted, don’t be discouraged. We still have meaningful historical data which will allow us to make process improvements. Using this information allows us to dig into the database. For instance, we would be able to see that an inkjet proofing paper from a vendor has a delta E variation beyond what a printer is willing to accept over a month’s time. The key is that process changes will be made based upon objective fact and not subjective opinions.

The process changes made will continue to improve the ongoing process, which will result in fewer and fewer defective proofs. Each defective proof no longer being made has a cost savings associated with it. When you add up all these little cost savings, you can quickly calculate the return on investment of your hard copy, color proofing process control software solution. In our experience, the entire cost of the ProofPass system is recovered in less than one month in many cases.

Proper Press Fingerprinting Takes Commitment

by Shelby Sapusek on February 24, 2011

This post originally appeared on JimRaffel.com on March 21, 2007, and has been repurposed for this blog.

In this installment, we will address the third question Dale raised in #47. Dale’s first two questions were answered in #48 and #49 which can be reviewed at JimRaffel.com.

Now, on to Dale’s third question:

3. In fingerprinting our presses, we’ve run up against the dreaded “Hurry up and do it, but don’t put too much work into it.” What are your recommendations for impressing upon the higher-ups that doing color balancing and working out the calibrations takes time?

The reality is that the culture required for completing successful fingerprints starts at the top and does not get worked up from the bottom. I spent the better part of the first 10 years of my career trying like heck to change the culture of a printing company (now out of business I might add) from the echelons of lower and middle management. While I hesitate to use the words “can’t be done,” I believe this is one place where this expression applies.

I have been very fortunate in my career. At 21 years of age, before I had even graduated from RIT, I was able to observe one of the press runs used to set the early SWOP press standards. A lot of very smart people participated in this run and the scientific procedure was impressive. Then, not a year later, I was the guy doing all the print quality measurements on a brand new Baker-Perkins G14 that cost about $9 million back in 1986. While I was just one member of a very large team, the owner of the company made it quite clear that he was not making his first lease payment until we had a press that was printing correctly.

Over the next 3 years, I had the same responsibility as two more new presses started up in that facility. In both cases, the purchase contract was very clear that we did not make lease payments until the press met our print quality standards. While the company in general had a difficult culture, all three of these press startups received a message from the very top of the organization of “Do whatever it takes to get a solid press fingerprint.” The reason was simple: Without a solid benchmark at startup, how could we ever know what condition the press was in later?

It takes a great deal of time, money and a great team to perform a successful and meaningful press fingerprint. During the press startups above, the fingerprinting process could go on for a week or more. The press was fully crewed and lots of paper was run during this time. All the support staff had to be available from prepress, plating, maintenance, materials handling, etc. I don’t think it’s an understatement to say that these fingerprint cost $100,000 or more.

Now, not all fingerprints need to cost that much. I took part in a very successful fingerprint within the last 30 days that probably cost no more than about $10,000, including our software and professional services time. It is, however, a matter of scale. The client for the $10,000 fingerprint was simply making the first investment in end-to-end color process control. All the key players in this organization participated in the meetings and remained onsite during the two days required to complete the fingerprint.

The results on the second day (and in followup calls over the last three weeks) continue to be impressive. In the case above, the press is not brand new but instead a fairly old and well-worn piece of iron that is now printing at an impressive level.

My conclusion is simple: If senior management of a PRINTING company is not willing to invest the time, money and effort necessary to perform a proper PRESS fingerprint, one must really question the value of performing the fingerprint.

Let’s start by breaking down the title of this post. “bright future” implies that past brand color management practices have not delivered desired outcomes – true. “Brand color” refers to the precise color the brand owner is expecting to be reproduced regardless of substrate, print process or geographic location. “Management” is the meat of this [...]
