How to choose the right mesh count for the job
Mesh count affects how much ink passes through the screen and how fine the detail can be. Lower counts are usually used for heavier ink deposits, blocky artwork and special effects, while higher counts suit finer detail, halftones and cleaner edges. The right choice depends on the artwork, the ink type and the substrate being printed.
As a practical guide, a shop printing bold spot colours on fabric may use a different mesh count from one handling fine line work on coated boards or detailed graphics on garments. If the stencil breaks down too easily or the print looks flooded, the mesh may be too open. If the image looks starved, the mesh may be too tight for the ink and artwork combination.
- Use lower mesh counts for thicker ink deposits and simpler artwork.
- Use higher mesh counts for fine detail, small text and smoother print edges.
- Match the mesh to the ink, not only to the design size.
- If you are unsure, compare the current screen with the print result before replacing it.
Checking whether a frame should be re-stretched or replaced
Many frames can be re-stretched if the aluminium is still square, clean and not warped. Re-stretching is often the practical option when the frame body is sound but the mesh has lost tension, been damaged or no longer gives a clean print. If the corners are loose, the frame is bent, or the profile has damage that affects holding power, replacement is usually the better choice.
Before deciding, look at the frame edges, corner joints and surface condition. Mesh that has been patched more than once or has pulled unevenly can cause registration issues and poor ink release. In coastal conditions, or in workshops where screens are washed and stored frequently, corrosion, residue and damaged adhesive areas can also affect performance.
- Re-stretch when the frame is still true and the old mesh is the problem.
- Replace when the frame is twisted, cracked or no longer holds tension evenly.
- Check for glue residue, dents and damaged corners before sending a frame in.
- Ask for a clean prep if the frame has old adhesive or ink build-up.
What proper tension looks like on a working screen
Good tension gives a cleaner snap back after the squeegee passes and helps the screen release ink more evenly. Too little tension can cause smudging, poor registration and blurred detail. Too much tension can stress the mesh, shorten screen life and put unnecessary strain on the frame.
For consistent work, the screen should feel firm across the full print area, not tight in one section and soft in another. Uneven tension often shows up first on long runs or repeat orders, where the print starts looking different from one screen to the next. A quick tension check before dispatch can save a lot of time on press.
- Look for even bounce back across the full mesh area.
- Check that the corners and centre feel consistent.
- Test old screens again if prints begin to drift or blur.
- Keep notes on which mesh count worked best for each job type.
Measuring frame size before placing a replacement order
Getting the frame size right is just as important as choosing the mesh. Measure the overall outside size, then confirm the internal print area that your press can handle. A frame that is too large may not fit the clamp or platen, while one that is too small can limit artwork placement and reduce usable space.
When sending details, include the frame dimensions, the mesh count you want, and whether the screen is for garment printing, signage or mixed use. If you already have a working screen, matching the old one is often the easiest route. If not, a fresh size check helps avoid delays when the job reaches press.
- Measure the outside dimensions and the usable print area.
- Check the frame thickness if your clamps are limited.
- Confirm whether you need a new build or a re-stretch on an existing frame.
- Keep the same frame format for repeat orders where possible.
When the print is not behaving as expected
Some printing problems come from the screen rather than the artwork. If ink is flooding under the stencil, the mesh may be too open, the tension too low, or the stencil edge may have broken down. If detail is missing, the mesh may be too fine for the ink load, or the screen may not be releasing properly. A quick inspection can show whether the issue sits with the frame, the mesh or the setup on press.
Common signs include uneven prints, drag marks, pinholes, weak edges and inconsistent repeat results. If the problem appears after washing or storage, check for moisture, dirt or residue on the mesh. In Gauteng workshops especially, dust and handling marks can build up faster than expected.
- Inspect the screen before assuming the artwork is the problem.
- Look for blocked mesh, broken stencil edges and uneven tension.
- Check whether the issue appears on one screen or all screens.
- Clean and prep the frame properly before the next run.
How to send the right details for support and replacement work
To speed up support, send clear details through the enquiry form on our contact page. The more accurate the information, the easier it is to match the mesh count, frame size and finish you need. If you are replacing a batch of screens, keep the specs together so the order stays consistent.
Our team in Germiston supports print shops across Johannesburg, Pretoria, Durban, Cape Town, Gqeberha and surrounding areas, with delivery routes arranged for regular supply and repeat orders. Whether you need new frame stretching, re-stretching, mesh count matching or screen inspection, the goal is to keep the screen ready for use without unnecessary back and forth.
- State the mesh count, frame size and intended print use.
- Include whether you need new stretching or replacement only.
- Tell us if the job is for a repeat order or one-off work.
- Add any setup notes if the screen is for a specific press or clamp type.
