Plastisol – Wikipedia, the free encyclopedia

We all know about Plastisol as a ink but did you know where else it is used?

INKS_BOXPlastisol is a suspension of PVC particles in a liquid plasticizer; it flows as a liquid and can be poured into a heated mold. When heated to around 177 degrees Celsius, the plastic and plasticizer mutually dissolve each other. On cooling the mold below 60 degrees C, a flexible, permanently plasticized solid product results.[1] Aside from molding, plastisol is commonly used as a textile ink for screen-printing and as a coating, particularly in outdoor applications roofs, furniture and dip-coating.

All about discharge inks – Updated

How can I print light designs on a dark garment – All about discharge inks.

I want to print light on dark?

I want a soft touch?

What is a discharge ink?

Here at Wicked Printing Stuff we don’t expect you to know everything and we are happy to explain things. Have you checked out our FREE buyers guide there is lots in there for the Rookie, Intermediate and Professional. Please give us a ring and explain your problem and we will help out. Lastly there are our training courses, designed again for both rookie and advanced printers with basic training or advanced courses.

So back to the problem. You want to print a light colour on a dark garment and you want it to feel soft. Now plastisol inks wrap colour AROUND the threads but gives a rubbery feel (also referred to as hand) but is bright. So ideally you want a water based ink. For those of you that have tried this and I can hear you shouting at the back, but I have tried waterbased inks and I just can’t get a good opaque print, that’s why I use plastisol. Well that’s where the discharge inks come in!

Punk rockerFor the punk rockers out there, remember how you got that bright green hair, that is right you had to bleach out your own hair colour first so the back ground colour was white, only then the colour would take and be vibrant and striking. It is almost the same in screen printing but we use discharge inks that need curing. The discharge ink actually removes the dye.

First off you have to have the right garment fabric, it has to be 100% cotton and it has to be dyed with a dischargeable dye. So check with the manufacturer. If the garment is a mixture of cotton and polyester only the cotton will discharge. Now that might actually suit you but you would need to do a trial run to make sure you get the effect you want.

Discharge processSo having got the right garment now we need the right ink. There are a lot out there and some are more complicated to use than others.

Water based dischargeable inks are the easiest and most eco friendly ones to use. The process works during curing when the discharge removes the original dye and the ink gives the new colour. To do this you add activator to the ink which ensures you get an intense colour.

 

Fuji MagnaColours

We have now introduced two Water based Discharge Ink ranges the patented MagnaPrint® Discharge ULF Ultra range of inks which are Formaldehyde Free and Soil Association Approved and Oeko tex class 1 and class 2 approved. This is the only system which does not stipulate that the garment has to be washed prior to wearing and is low odour compared to over discharge systems. The second system is Sericol TexCharge the largest ink manufacturer, TexCharge is Soil Association approved and also includes a colour matching system.

We also offer MagnaPrint Plascharge additive which you mix 50 / 50 with a plastisol ink, so if you are a plastisol printer you can take advantage of discharge technology.

For the discharge process to work, you do need a tunnel dryer (the longer the better) – typically 90-120 seconds dwell time is needed for a good cure. You can also use a heat press which is great for low production. You also need well ventilated premises and printers should read the MSDS and be aware of any health and safety consideration.
We would be delighted to talk you through this if you have any questions, please contact us.

Blacquer Ink

Do you want to save money on film positives?

The Blacquer Ink is a unique product developed to help you create fantastic high quality film positives at an amazing price.  Blacquer has been developed to produce the most dense black film positives on the market, increasing the quality of your screens in production.  You don’t need specialist RIP software,  just the standard RIP that comes with the printer.

Remember our sneak preview:-

The use of inkjet printers to create screen positives is not a new idea. We have all been using this technique for a number of years. However, at Blacquer from  we have developed an ink to specifically target this area. At Blacquer we were looking at various printing technique and one thing that struck us was how many small and medium size screen printers are using OEM (Original Equipment Manufacture) inkjet inks to print film output for screen positive print production.
We have all read the press in recent years about how much OEM inkjet ink costs in articles like this
We decided that there was a gap in the market to create an ink which is directly targeted towards the production of screen positives rather than use an OEM ink to fit around the job. The idea was also that the ink we produce would be available in bulk bottles, so the cost of the ink is dramatically reduced when compared to OEM products.
At Blacquer we have produced a pigment based black ink which has been designed to maximise the blocking of the UV light which is used to initiate the reaction of the screen emulsion. The black pigments we use are the highest quality available on the market and designed specifically for inkjet applications. We have a vast knowledge of how to produce inkjet inks and have used this expertise along with the highest grade raw materials to produce an easy to use product producing spectacular results.
The inks have been designed to work through Epson print engines. We will be developing inks for other printers in the near future, but one step at a time! One of the starting models we recommend costs less than £250, so it is not a large investment if you do not already have a printer in house suitable for this application.
We initially sell the ink in cartridges, but these cartridges are refillable by hand. Therefore, you are paying a reasonable amount for the ink (unlike with OEM cartridges). We have calculated that the cost of ink on an output film with Blacquer ink is around 8 times less than using OEM ink! Think how much this can save over the year.
We are very happy to partner up with Wicked Printing Stuff and proud to have them representing Blacquer ink. We feel the support and knowledge they pass on to their customers is exactly what we need from a partner with this product.

Blacquer ink is designed to use the Epson Printer Range, initally focussing on the 1500W with more models becoming available.  The ink is available as refillable cartridges or in bulk.

We have worked closely with Blacquer to get the ink just right,  we use the system ourselves and are totally impressed with the results.

We sell the ink, printer and the Blacquer film range ….

Glow in the Dark – Screen Printing Inks

One of the more unusual screen printing inks – Glow in the Dark.

How would you use a Glow in the Dark screen printing ink?

Glow In The Dark - GreenThe WPS glow in the dark ink range is effective in complete darkness, when it will radiate a bright colour. This ink is fantastic for giving your prints that something special.

Glow in the dark green ink is a high quality ink that radiates a bright lite-green colour in darkness.

For best results this ink needs to be printed over a white coloured base. Heavier ink deposits will result in increased brightness and a longer “after-life.”

Best printed through a 32T or lower mesh count.

In daylight or artificial light conditions, this ink will have a pale off-white hue. The ‘glow’ is not noticeable under natural light, but the glow particles in the ink charge up in daylight or under fluorescent lighting to produce a strong glow in the dark.

How to use glitter inks?

glitterGlitter designs add umph to your designs. Just a couple of things to look out for.

As glitter inks require a coarse mesh so the design should not be too detailed. They are best used for a large, block image rather than small wording. This example is perfect for glitter but a small intricate design would not work as well.

When creating your screen use solvent resistant dual-cure emulsions. You want 15-25T (8-10T metric) monofilament for direct printing and for transfer printing use 25-33T (10-12T metric) monofilament. Your squeegee should be solvent resistant and hard we recommend Wooden Squeegee with D Cut ( V Cut) Blade.  Ideal for textile printing with plastisol ink. D cut blades lay down a heavier deposit of ink.

Plastisol inks will not air dry. They must be heat cured. When fully cured the ink will withstand repeat washings.

The oldest Ink – #tbt

The history of Chinese inks can be traced back to the 23rd century BC, with the utilization of natural plant (plant dyes), animal, and mineral inks based on such materials as graphite that were ground with water and applied with ink brushes. Evidence for the earliest Chinese inks, similar to modern inksticks, is around 256 BC in the end of the Warring States period and produced from soot and animal glue.[5] The best inks for drawing or painting on paper or silk are produced from the resin of the pine tree. They must be between 50 and 100 years old. The Chinese inkstick is produced with a fish glue, whereas Japanese glue (膠 “nikawa”) is from cow or stag.[6]
