Arvest Impressions:

An inside look at the printing process

 
 
In Armenian, the word Arvest means "art". At Arvest Press we love what we do, and treat each new printing project with the artistic care of a skilled craftsperson. This passion translates to a high level of customer satisfaction, and top quality products.
In the Pressroom: Ready, Set, Makeready.

 

 

Bringing a job up to color:

 

Makeready, in print jargon, refers to the steps a pressman takes in order to get each print run ready for the press. At a basic level, it means things like hanging plates on the press, making sure the paper is cut to size and filling the ink wells. But offset printing also requires a certain amount of finesse to get the press up to speed for the full print run, and a skilled pressman can make all the difference in how quickly the Makeready is achieved.

 

Once the paper is loaded and the ink and water balance established, the pressman has to set the ink zones for the rollers. Each area of the press is divided into zones, and each zone is fed by an ink duct and controlled by an ink key. With technological advances in the printing process, it is now likely that the pressman starts with a CIP3/CIP4 ink definition file which will set the initial keys for the job. The pressman will then run a small number of sheets, take densitometer readings manually or use a color bar reader, and make adjustments to the various keys. Each press is different, but the goal is to run to a measured ink density. The pressman uses the color bars on the sheet to measure the density of each ink.

 

Once satisfied the inks are running to the proper density or "to color", he or she will then run more sheets and tweak the color as needed. Once the pressman is confident the job is ready to go, he or she will proceed with the full print run, but will still pull a sheet now and again and measure the colorbars to check the concsistancy of the printing throughout the entire run and job. Using a set density goal makes it easier to keep the color in multiple sheets of a project properly balanced and ensure the run stays uniform.

 

Setting the right ink density is an especially important practice when it comes to crossovers in a booklet, images, graphics or text that begins on one page and crosses the spine of the book to another page. Typically crossovers are not on the same printed sheet, so two different sheets will be joined together later in the binding process. Any fluctuation in the color would be immediately noticable.

 

At Arvest Press the combination of our technology and the skill of our press people helps to maintain a level of consistency we are proud of and keeps your project on budget and on schedule.
