USING A WHITE UNDERBASE

Today I have been busy printing transparencies, coating screens, burning screens and washing out screens.  Did I miss something?  Oh yeah, blowing out screens.  I was down to washing out my last screen and I blew out the image.  Ugh!!  I had to start the whole process over again.  It was my first blow which is not bad.

I will be printing hot pink ink on black tote bags.  I do not want to print a ton of hot pink ink so I am going to do a white under base.  Basically I am printing the image twice, once in white ink (because color shows truest on white) and then a second time in hot pink.  The white under base will allow the hot pink to really pop on the black background.  I guess this could be considered a two color print because I will be using two screens and I must line up the image with my registration marks. 

I printed two transparencies for this job.  The first transparency was the original design.  I printed the image again on a second transparency but I did a CHOKE on the whole image.  What that means is you are choking your image back, making it a little smaller then the original image.  This makes registration easier because you have a little room to maneuver.

I have been confused as to what exactly a CHOKE, STROKE and TRAPPING means and how to do it in CorelDraw.  I searched on the Internet for months but could not find an answer anywhere.  I called Ryonet a few days ago and spoke to TJ.  TJ IS AWESOME!!!  Finally someone could give me an answer. 

The fastest way to do a CHOKE in CorelDraw is to place a 1-2 point outline around your image and make the outline white.  The outline goes half way inward and half way outward.  When you go to print your transparency, CorelDraw will not register the white ink.  So a 2 point outline will shrink you image by 1 point.  It was very fast.  I did have to play around with the size of the outline since some text was smaller then other text.

Time to coat more screens!
