When a race car driver wins a race and stands at the podium to accept the coveted prize and recognition, he gets the praise, accolades and the headlines. But how many people’s shoulders do you think he is standing on – a few a dozen? Hundreds?
There is the team that sets up the suspension; the team that built the engine; the team who chose the tire durometer…The fuel mixture? How about the team who built the transmission etc. The point is that once the driver sits in the driver’s seat, there have been thousands of hours and decisions that have been made in order for the driver to even have a chance to win.
At a recent seminar about special effects printing, I spoke about how each tool used in screen printing has its purpose and why its upkeep and maintenance is important to the end result: A great print!
I used a racecar analogy to illustrate my points:
It costs a lot to design and build a racecar, and each component used in the car has a purpose, whether it’s a lug nut to secure the tire or a seatbelt buckle to hold the harness in place – once you are setting up a design on the screen press, many decisions have already been made and the printer’s experience in printing the design can make the print a winner or a looser depending on all the prepress preparations.
Are the screen tensions up to snuff (tight)? Are the squeegees sharp and the durometers correct? Is the emulsion thickness enough? Is the film opaque enough? These are just some of the prepress preparations that need to be made. Why is it so important to get the prepress prep done right?
Let’s say that some of the prepress decisions weren’t working out on the press, what do you do? If you need just a little extra ink deposit on one color for example, can you re-burn a screen if the mesh opening isn’t large enough? Not ideal, but it’s possible – if time and money isn’t an option. However, if you have a selection of squeegee durometers on hand to choose from, you may be able to save yourself some time and select a lower durometer squeegee (softer) and get away without having to re-burn the screen with a lower mesh count.
In another scenario, when printing a white design on dark fabric, did you consider adding an extra coat of emulsion on the white under-base screen? That could really help with the opacity of your white inks.
Here’s why the little details in prepress matter: If you had a press in your garage that printed dollar bills, would you let it run out of paper – or ink? Would you have critical spare parts ready if needed? Well if you are a screen printer, you arethe machine in the garage that prints dollar bills. I’ve been in that position, and I had to make sure I did everything I could beforehand to guarantee that my machine was printing as many dollar bills and for as long as I could.
Just as in a race, you can’t win the race if you can’t start or finish. So starting the print run as soon as you can with the proper preparation assures that you will stand in the winner’s circle at the end!

Why do we often struggle with some of the seemingly simplest things, like slathering screen-printing ink onto a decorated-apparel garment. Slathering so that it looks clean, bright, opaque and altogether attractive.
