Yudu Home Screen Printing Kits

Yudu Screen printing techniques primarily require a fine mesh or screen securely stretched around a stiff casing.

Screen printing is very easy. It can be a pleasure and provide great satisfaction in seeing a print job done well.

In fact, if you iron out most of the bugs and kinks in your screen printing process it is possible to teach almost anyone to print well.

The right equipment can make a difference.  Here is one suggestion that will work for most home screen printing.

Yudu Screen Printing Machine-USA 62-5000

Fun and easy to use, this personal screen-printing system allows for creating custom designs to embellish t-shirts, backpacks, and other apparel, as well as home decor, posters, greeting cards, schoolwork, and more. The system comes with a printing machine, a mesh screen, an emulsion sheet, a squeegee, an adult t-shirt platen, a platen adhesive sheet, a blank ink-jet transparency, and a 2-ounce bottle of black ink. Choose the artwork to print from a variety of sources: draw freehand-style on a transparency with a permanent marker, purchase ready-made, cut paper by hand or with a Cricut cutting machine, or run a transparency through an ink-jet printer for any text or icon imaginable.

Place the desired artwork on the machine, cover with the mesh screen (with emulsion sheet attached), close the lid, and push the exposure button to burn the selected image onto the screen. After rinsing the screen clean and drying, place the t-shirt or material to be printed on the machine (tacky platen holds it in place), set the screen in the lid, flood the screen with ink, and close the lid. By pulling the squeegee over the screen, ink transfers through the image to the t-shirt below. Create multiple prints and multicolored designs, all with professional-looking results. The machine provides a user-friendly control panel with a digital display and buttons for the drying fan and the eight-minute burning function. An instructional DVD and a user manual come included. The personal screen-printing system measures approximately 32 by 21 by 11 inches.

Yudu Screenprinting – Three Causes of Yudu Screen Fails

Yudu Screenprinting – Three Causes of Yudu Screen Fails
By Gary Jurman

If you have been experimenting with the Yudu Personal Screen Printing Machine by Provocraft, you may have run into several problems when trying to print your images on Tshirts. One such problem is getting thin lines or small type to come out right.

Here are 3 of the biggest factors making it difficult to get fine details with Yudu screens:

  1. The mesh of the screen itself is simply too low resolution to hold the image.
  2. The squeegee used to pull the ink is poor quality.
  3. The frame of the screen is too flimsy to hold adequate screen tension.

Screen mesh comes in a variety of resolutions (known in the industry as “mesh count”) from 33 or less all the way to 300 and higher. Commonly, among screenprinters who don’t do a lot of specialty work, three mesh counts are used: a low resolution, a medium, and a high.

Low resolution (around 110 mesh) screens are used for thick inks, light colored inks (like white and athletic gold), and for low detail prints. They are generally easier to get the ink to flow through and less expensive than their higher resolution counterparts.

Medium resolution (around 160 mesh) is used for smaller type (down to about 12 point) and thinner lines (down to about 1 point). If you have a good method for making your stencils or a good burning unit (used for exposing your screens), the medium resolution can serve as a sort of most-purpose screen.

Higher resolution screens range from around 190 and go up from there. They are able to capture very thin lines and small dots, and when used in conjunction with automatic screen printing presses can even achieve photographic quality images.

So what kind of screen comes with the Yudu? Not a medium resolution, but a low resolution mesh count, a 110. Even if the screen was perfect in every other way, a 110 mesh simply does not hold thin lines and small type.

Like screen meshes, squeegee blades also come in a variety of types. While there are many aspects of squeegees, including handle characteristics, blade structure, and composition, our main point here has to do with flexibility. Since the Yudu is designed for manual screenprinting, and it is for general purpose use, let’s examine what makes a decently flexible most-purpose squeegee.

The flexibility of a squeegee is known as durometer within the screen printing industry. Most suppliers carry three durometers of blade, a soft (60 durometer), a medium (70), and a hard (80-90). While the softer is used for laying down a larger volume of ink, the harder varieties are used to achieve more detail and also for depositing a thinner layer of ink.

If a screenprinter were to choose a most-purpose squeegee blade for the kinds of screenprinting you are likely to do with the Yudu, he definitely would need one in the scope of the medium or 70 durometer. If you want to be able to pull most general purpose inks through a screen holding most general purpose images, the medium is your best choice. What durometer is the Yudu squeegee? Provocraft doesn’t specify, but whatever it is, it’s less than 60 for sure, and 60 is not hard enough.

Finally, even if you re-stretched the screen with 160 mesh and bought a professional grade squeegee of medium durometer, there is still yet another problem that hinders quality screenprinting with the Yudu screen: screen tension.

While screen makers do have their own custom tensions for screens it may be sufficient to note that lower tension screens make for smeary imprints and lower quality images. They also make it tougher to do multi-color imprints, which is somewhat moot because the Yudu is not designed for it in all other aspects. Lower tensioned screens lead to a variety of screenprinting issues because, if the mesh is loose enough, it snags and drags along with the squeegee when the print is being executed. Even if the screen has a good stencil with thin lines in it, that line is smeared and dragged along when the squeegee passes, causing a blurry image. How does the Yudu screen hold up when it comes to screen tension? Even fresh out of the box, the Yudu screen is way under-tensioned for even the most casual screenprinter.

Given the limitations described with the screens used with Yudu Personal Screen Printing Machine, one may wish to limit the types of imprints they choose to try using the system. Many hobby screenprinters have expressed a sense of success with the Yudu when they stick to thick lines (3 points or more) and large typefaces (20 point and up) in their designs. It also may be helpful to upgrade the squeegee to one using a professional grade squeegee blade. While your results will vary according to your skill level, it certainly will be easier to get more crisp images and achieve greater success. If you find the aforementioned limits unacceptable, however, you may wish to use a different system with more versatility.
