Important Tips for Choosing a Press for T Shirt Printing

08Sep

There are two factors that pose a threat to the efficiency and quality of a screen printing operation, the parameters and the type of equipment. The information culled from TShirtProfessional is to assist you in purchasing, selecting and setting up a screen printing business.

Presses

Printing equipment, automatic or manual is required to possess some form of capabilities before they can be employed for a business operation. The following checklist below will assist you in identifying the features that are essential and the differences between the types of presses I included.

Registration: This is when special systems and techniques are combined in order to align colors more precisely.

A manual press is typically fitted with one of two types of registration systems, which is either the nylon belts or the adjustable no steel ball bearings. In the case of ball bearings, the hardened steel ball is fitted with each of the screen support arms. The bar in the placed between two ball bearings made from hardened steel as the print arm descends low into position. In order to be easily tightened to the keel, these bearings should have a side by side adjustment, just as the material wears.

On the other hand, nylon belts operate somewhat similar to steel ball bearings, in the sense that the screen support arms are stuck between two nylon bolts. In order to apply sufficient arm tension, the bolts can be adjusted in and out.

One other area that can affect the registration of manual printing equipment is the side screen holders. This system clamps the screen from each side, as opposed to the rear side of the frame. The benefit of side clamps is that it provides stability for any type of screen, most especially when you are using wood frames.

Automatic presses make provision for more accurate registration that manual presses. Most automatically operated presses use a system of cam followers or hardened steel ball bearings to position the pallets using a V- shaped or U- shaped capture. The pallets employ an indexing system for their coarse alignment, while the final alignment is achieved when the bearings are being trapped by capture. Multiple captures are observed with presses with a high degree of accuracy.
