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.
Next Steps: Behind the Curtain - Prepress


The Prepress Department:


So you've crafted a beautifully designed piece and gathered up the files, support graphics, images and fonts. You've pulled your bleeds, and made sure the work had a safe margin all around. Perhaps you're confident your revision process is complete, so you've generated a "Print Ready" PDF file. The files are on a thumbdrive, disc or zipped and ready to send over the internet. You deliver the job to Arvest Press.


Now what happens?


First, we open your files up and check all the same elements. Images, graphics, Bleeds etc. Then we run the file through a RIPing software, in Arvest's case we use a Rampage RIPing system, which processes the file and gets it ready for the platesetter. The most important part of the RIP process is trapping the piece.


Trapping is simply making sure the elements or colors that are top or beside each other, touching in some manner, have a miniscule amount of overhang where the colors meet. This is so any natural movement on the press rollers is accomodated for. Similar to a bleed but much smaller. There are two basic types of traps, a choke and a spread.


Using a simple example of Blue text on a tan background, if there was no trap and any shift on the press, there might be a slight gap which would expose the paper beneath or leave a halo effect where the two elements had common color. In this case we would "choke" the tan into the darker blue to create a shared area that is barely visible, but keeps the paper beneath from being exposed and also the text from looking "fatter", which in smaller font sizes might plug up around certain letters. Reverse the color scheme, tan text on a blue background, and we would "spread" the tan text into the darker blue for the same trap effect.


Next on the Prepress list is to generate a "proof" for the client. Because the RIPing software is able to deliver a proof that exactly matches what will be printed it is important to treat the proof as if it is the finished piece. This is the last chance to make sure everything is correct before it goes to press. Finding a mistake after a job is printed, or in the middle of a press-check (we'll cover those in a later blog) can lead to costly reprints or down time on the press, which the client would be responsible for. The proof is one of the most valuable tools in the printing process.


Once we have that final approval for the designed piece, we can then send that same RIPed data to the plate setter and generate plates for the printing press. Your job is now ready to be printed!
