All the printers like to print high-quality prints with their screen printing machine. For high-quality images printed, you should be careful with your screen tension. It is one of the most crucial pieces of equipment to offer high-quality print.
If the tension of the screen is inappropriate, it will produce lower-quality prints. As a result, you are to decrease your marketing capability. Luckily, by taking some steps, you could set your screens up for the most favorable presentation.
Imagine you start printing with your screen printing machine, but you find prints are blurred, messy, or defective. Immediately you become suspicious about your artwork along with the screen printing machine. Through a vivid investigation, you find a setup of your artwork. This setup is acceptable for quality, and at the same time, your printing machine is working as usual. But you care little about your screen tension which could cause immense trouble.
The Effect of Improper Tension of Your Screen Printing Machine
Screen tension is the tight state of the mesh in the frame. Newton per square centimeter (N/cm2) is the standard measuring tool. Suppose the screens lose their tension repeatedly, and it hampers. It would help if you blew the squeegee straight and perverted the mesh. Total printing jobs could suffer from this sort of unacceptable tension.
Unacceptable tension can affect your screen printing machine and make your print defective. You have set flawless artwork, and your film has a proper alignment and better print. You get archives of solid rock from your machine, but you are producing crooked prints. It appears to be due to the defective tensioned screen.
The poor screen tension exaggerates the integrity of your stencils. These inappropriate screen tensions would result in quicker fracture down of stencils. It happens due to the placement of the mesh under unnecessary strain. Feedback of a decadent stencil are pinholes, fuzzy edges, and loss of detail in your prints.
If your screens fail to preserve appropriate tension, your prints can spread as the ink may gather in mesh folds and not extend consistently.
Screens with short tension are prone to pick up ink from preceding layers of a multicolor printing job. They do not crack back into the spot as they should when the squeegee goes over. The preceding ink can construct and chunk openings of the mesh. It holds succeeding layers of ink from fleeting through the screen, resulting in blurred prints and thrashing of detail.
The manual screen printing machine gets an additional complication because of utilizing extra squeegee weight to find the ink from the beginning to the end of the screen.
For Proper Screen Tension, You Require to know the Below Measures:
What is the exact number?
The tension between 25 and 35 N/cm2 is appropriate. However, it would help if kept away a minimum of 15 N/ cm2.
The process of finding screen tension:
To measure your screen tension you can use a tension meter tool to measure the screen tension. It stays on the print side of the screen and tracks out the quantity the mesh offers under its load. When measuring, you need to place the net on a flat, level surface. One place measurement is not competent for reliable results to verify all over the screen to have certainty that the tension is identical. Conform measuring the tension in two directions, from top to bottom of your screens and from one side of the screen to the other.
Measures to preserve appropriate tension:
If your screen tension gets less than 15 N/cm2, adjust the tension of your screens using the proper tools. A screen stretcher is a device you can use either manually or with pneumatic clamps, so your mesh gets back up to appropriate tension.
If you are unwilling to add extra tools, applying roller frames can make the work even smooth. Again if you don’t like to do it yourself, there are professionals you can send your screens there.
Type of Frame and Mesh Hight:
Remember, the type of frames you use determines your screen tension. Moisture or temperature changes will let the wooden frame offering lose tension.
The adhesive you usually use to keep the mesh to the metal frame could get demoted after passing the required time. As a result, you would get unacceptable tension. The Roller frame also gets losing the effect of its grip on the mesh after passing the standard time. It is wise to check regularly to find whether achieved exact tension. And regulate as needed.
For your printing press, some supplementary take measures so that you can achieve the required tension. It’s better to use the least quantity of off-contact likely and be sure that your screens and pallets are level and parallel. As a result, less squeegee pressure is to be needed. This less pressure will reduce the stress on screens and let your squeegee move more quickly. For this, you will receive prints with the required speed, quality products, and efficiency.
On the contrary, very high screen tension will also cause trouble.
Expanding the mesh too strongly will make your screens more vulnerable to spoiling for the period of printing and possibly harder to print all the way through in case of using a manual press.
