The images on my screens are not washing out correctly, why?

This can be for a number of reasons, here are a few things to watch out for:

  • That you are doing all parts of the emulsion and exposure process in a light safe environment with NO outside or bright light. This includes mixing your emulsion, coating your screens, drying screens, exposure, and washout.
  • That you are not coating your emulsion too thick. One coat both sides should do it, with a nice even spread. There are sometimes where you may need some extra coats e.g. printing transfers and printing white onto a dark garment but you will need to adjust the exposure time.
  • That your film positive is very opaque and dark. If you hold it up to a light and can see through it, you need to double print your film to achieve a more opaque image.
  • That there is positive contact between your screen mesh and your positive film. If the film is not pressed completely against your mesh then you will get light reflection between your positive and your screen which will result in a blurry and not clear image. That’s why the glass is so important.
  • That you are exposing your screen for the correct amount of time, which will depend on the exposure system you are using. If you are unclear on exposure times please feel free to ask us. The simple run of thumb is – if the emulsions washes off too easily and you start to lose the stencil then the screen is underexposed and if after prolonged washing the stencil does not come through they you are likely to have overexposed the screen.

What is the difference between Serigraphy and Screen Printing?

What is the difference between Serigraphy and Screen Printing?

Actually there isn’t any really, the process is identical, you might almost call it a snob term. Exactly like printing on t-shirts it involves screens and inks however it is often used to refer to fine art rather than garments. Sometimes the results can be limited edition runs, hand printed by the artists and then the design is destroyed. This is one I found on the internet searching on serigraph limited editions.

Do you want to get an embroidery effect?

Looking for suede look?

Puff inks contain an additive that causes the ink to swell as it cures for a high-density effect. Often used for an embroidery effect.

Suede inks swell to a smaller height and create an effective imitation of leather suede.

These are best used in small parts of the design so they are stand out more and the additive can be used on any colour in the range. Have a browse on Pin Interest to get some ideas, I got these images there.

 

Stencil Strip

Finished with your design and want to reuse the screen?

‘Reclaiming’ is the act of striping the stencil from your screen in order to create a new strencil and start the printing process over again. WPS sells a variety of equipment and products for this process including dip tanks. Stubborn stains can be removed with Haze Paste.

Haze Paste remover is a great solution if you have any ghosting left on your screen which is common when using waterbased inks as they dye the mesh.

Our range includes :-

The premium MacDermid Autohaze, which is a high strength paste which deals with the most stubborn stains.
KC Haze Easiclean Remover, low strength remover ideal for removing light to moderate ghosting
WM Haze Easiclean Remover, moderate strength remover ideal for removing moderate to heavy ghosting
ES Haze Easiclean Remover, high strength remover ideal for removing heaving ghosting
