Complement the natural beauty of linen with shimmering PERMASET screen printing inks.

PERMASET Pearl White can be substituted for PERMATONE White when mixing inks to create shimmering colours. PERMASET Pearl White can be mixed with either PERMASET Standard Colours or PERMATONE mixing bases.

The PERMATONE mixing system can produce 1869 colours. Simply choose a colour, substitute 50% PERMASET Pearl White for PERMATONE White in the formula, mix thoroughly and you have a shimmering facsimile of the colour!

The photos shown above of light blue and mid blue samples on white and black cotton jersey show the effect of substituting PERMATONE White with 50% PERMASET Pearl White. There is a small tonal shift with the Pearl White substitution.

Not only does using the PERMATONE mixing system take most of the guess work out of formulating a colour it is also reproducible – just lookup a formula, substitute PERMATONE White with 50% PERMASET Pearl White and you can mix up another batch.

Shimmering blues printed on 100% linen in Oatmeal colour.

You may also have noticed that using PERMASET Pearl White instead of PERMATONE White adds opacity to the transparent PERMATONE mixing bases allowing you to print on dark fabrics without needing to print an underbase, saving you time and reducing your ink costs.

We also made up two greens for comparison,

and two reds:

While PERMASET Pearl White offers some opacity the final colour of the print will be influenced by the colour of the fabric.

PERMATONE mixing bases give you the versatility of a matching system and are water-based so are easy to clean up and after heat fixing, PERMATONE prints offer excellent wash, rub and dry-clean resistance.

PERMASET® SUPERCOVER First Down White is used as an under-base or flash white by Trade printers who wish to print on dark fabrics but prefer to use standard PERMASET AQUA® colours or PERMATONE® inks to retain their superior softness and vibrancy. It is normally used with multi-station print facilities.

Using PERMASET SUPERCOVER First Down White in place of a discharge product will mean you tie up an extra print station however, there are 5 great advantages:

1. TIME PRESSURE & WASTE

No chemicals means no smells, no rush and no waste with PERMASET SUPERCOVER First Down White.  With discharge printing, once you add the discharge agent the clock is ticking, so you must print the entire bucket within 2 hours. Any discharge ink unused at that time must be disposed of, so there’s a wastage factor with discharge versus using PERMASET SUPERCOVER First Down White.

2. WHAT YOU SEE IS WHAT YOU GET

With PERMASET SUPERCOVER First Down White you can see what you’re printing from the very first print. A complaint of discharge systems is that if a mistake IS made, you don’t get to see it until it comes out of the drying tunnel at the end of the process, by which time potentially 20 more shirts may have been printed.

3. HEALTH & SAFETY

The lack of chemical addition with PERMASET SUPERCOVER First Down White reduces an opportunity for the introduction of variability into your processes (e.g. in staff mixing practices +/or variability in dye-lots from the shirt manufacturer).  No chemicals, no smells and no headaches also contributes to a safer workplace for you and your staff and a healthier environment for your community.

4. REPRODUCIBILITY

You’ll get a more consistent result using PERMASET SUPERCOVER First Down White from one shirt colour to the next and one shirt maker to the next.   You don’t know whether this year’s black t-shirt was a surplus white shirt last year, or pink, or brown, or green or orange or purple, so you don’t know what colour it will come out with the discharge process.

The reduction in variability through printing one standard ink as a base onto a shirt puts you back in control; you control the inputs and processes so you get reproducible results.

5. SOIL ASSOCIATION APPROVED

Added to the above, PERMASET SUPERCOVER First Down White also has Organic Approval from the Soil Association in the UK. This means that PERMASET SUPERCOVER First Down White has successfully met the requirements of the Global Organic Textiles Standards (GOTS) for non-organic chemical inputs for use in organic textile processing.

So now you’ve got 5 solid reasons to explore this innovative technology.

Throughout the process of fabric printing using water-based screen printing inks, heat curing the print is one method to ensure the print is stable and can remain on the garment. Heat curing is subject to variability due to local conditions in the workspace; including the moisture content of the fabric, the ambient temperature and the relative humidity.

There are several practices involved when applying heat to fabrics to cure them.  We recommend test printing before and at the beginning of each print run as heat setting varies from printer to printer. When heat curing water-based screen-printing inks such as PERMASET AQUA®, PERMASET SUPERCOVER® and PERMATONE®, the following methods are used:

For screen printers who are just starting out, make sure that your prints are completely air-dry before heat curing, and testing should be done before embarking on a large print run. For this type of printing, you can employ heat press and flash dry methods.

1. Heat Press

Heat presses are a favoured option for start-up printers as they are compact to buy and quick to operate. They are recommended for small scale production as it takes time to cure each garment.

2. Flash Dry/Cure Units

Prints must be completely air dry first. Flash units are cheap, compact and quick however they can give variable results. The flash dry method is intended to dry ink to produce opaque colours or dry off colours to prevent smudging between print layers when printing multi-colour prints.

For home-studio printers, we recommend using these three methods: hand iron, oven bake and tumble drying to heat set the print.

3. Hand Iron Curing

Firstly ensure your prints are completely dry. When ironing Metallics, fabrics must be ironed from the inside or reverse side as the pigment in metallics limit the amount of heat going into the fabric. This is especially necessary when curing PERMASET SUPERCOVER® prints.

4. Bake Method

You can bake a print in the oven using a low heat temperature of 90°C or 194°F. Make sure to fold the fabric after air drying and wrap it in aluminium foil before placing inside a domestic oven.

5. Tumble Dry

You can heat cure a print by putting it through a tumble dryer.  This method requires 30-minutes. You should always test this method prior to curing all your prints this way.

6. Tunnel Dryer

For commercial and trade printers, employing the drying tunnel method is the best method. The tunnel dryer is also called a belt dryer, this method is the most common for professional screen printers. For PERMASET® inks, the recommended curing is 160°C or 320°F with a standard time of 3 minutes going through the tunnel.  Some print shops have success with shorter dwell times, again test this method and find out what works best for you.

Please Take Note
There are recommended temperature and time instructions for each product on the back of the PERMASET® packs to ensure you can properly set heat fabrics and garments.

When curing water-based inks in a Drying Tunnel or Belt Dryer, we recommend curing 3 minutes at 160°C or 320°F
