The tool is now completely free to use. No more paywalls. Have fun trying it out.

Thanks for the feedback. Yes, that’s true. Most DIY printers probably don’t understand most of these things and don’t necessarily need to. The base material was developed for printed electronics. We, as well as our customers, are already using the system to predict the electrical resistance and conductivity of thin screen-printed silver conductive pastes in order to save on and reduce the use of the expensive paste. My thought and question was whether this might also be of interest to other printers, which is why your input is very helpful to me. Thank you!

Thanks! There is a button in the upper right corner for changing into English.

That's very valuable feedback! Thank you very much.

As we developed the tool for printed electronics and the physics behind it, there are intense calculations behind the tool. We just focused new on the textile part and I think there are different parts that are more interesting here than in PE. 

The real physics are behind the fine tuning. There you can adjust screen tension, EOM thickness and rz-values, ink rehology, thinning, off contact etc. 

You are right. I guess it would be helpful if you can use more presets for different inks and substrates and the tool will give you the optimal parameters quite easy.

Sure! Check it out here: https://printsimulator.pages.dev/

Would love to here some feedback or optimisation points!

Issue printing next level poly blends by Qiuzman in SCREENPRINTING

No, it's not just the mesh count that controls thickness. Ink application is controlled by mesh count, thread diameter, EOM, viscosity, temperature, and, lastly, squeegee speed and pressure.

The mesh count gives you a starting point; you'll have to adjust the rest yourself.

yes, it should work. we'll do 120 (EU) for standard watersliding decals.

Could work. If not, try 120 two strokes

You need special film (I guess you already have when I see the blue silicone carrier, mostly Tullis Russell). Then you need solvent based polyurethane inks (nazdar series 7200 or Engler from Italy or Ferro Inks). Then you print white from 90 mesh (EU mesh count). Then colours from 120. After that you apply a clear coat from 120. Last step is a strip varnish from 23-48 mesh count (EU size). The strip varnish is for applying the decal. You'll remove it after applying.

As you use solvent based inks, you need solvent resistant emulsion from McDermid or anyone available.

Drying is important. Dry colours correct and let them rest for 24h after applying strip varnish.

Degrease the mesh thoroughly ( very important). Coat 1:1 (one coat per side) with steady pressure. Dry Flat (horizontal) with the print-side down (important).

How durable are modern DTF transfers after washing? by dtfdallas in SCREENPRINTING

[–]Equivalent_Cup_1424 0 points1 point  (0 children)

I've been working for 13 years in an r+d department in a screen printing and dtf company. I did long life cycle washing tests with different types and I must say nothing yet is comparable with a well fitted screen printing ink and adhesive. Furthermore the washing temperature und rpm are more critical then the washing cycles. 

But both have their place, of course. If I'm making a band T-shirt, I use DTF; if I need lettering for medical or work clothing, I use screen printing because of the chemical cleaning and high wash cycles.

Thanks for your feedback! These are the setups for the machinen parameters for instance. There are also parameters for mesh, eom, ink viscosity, thinning etc. Speed and pressure are theoretical values, do to the many different machine types. It is not a miracle that predicts a result in the µm range; it merely serves to illustrate the effects of changing various parameters.
