Matsui’s new 301 ECO-Series Water Based Ink System includes binders, pigments and inks that are specifically designed for today’s manual and high speed automatic screen printing presses. The eco-friendly, PVC free 301 ECO-Series inks offer environmental and practical advantages over traditional plastisol inks currently being used in high volume textile shops.
Clear and opaque ink bases are available and each is available as either a high elasticity variety, or a high mesh variety. Metallic and pearlescent bases are also available for glittery, shimmering effects.

Matsui’s 301 Eco series pigments are super-concentrated, water-based solutions that are available in 12 colors and black. All pigments can be added to any base, and can be mixed with each other. Matsui’s pigments are tested and rated according to JIS standards for light resistance, water resistance, dry clean inability, and heat resistance.
What is the pot life of the 301 Eco Series inks?
The 301 Eco Series of inks are reusable so long as they are kept in airtight containers. However, any ink that has Fixer WF-F in it has a pot life of about eight hours.
What are the recommended curing conditions?
Ideal curing conditions are 320∘for 3 minutes, unless Fixer WF-F is used. If Fixer WF-F is used then the ideal curing conditions are 285∘F for 3 minutes.
Should I use Fixer WF-N or Fixer WF-F?
Inks with Fixer WF-F can be cured at a temperature of 285∘F for 3 minutes. However,Fixer WF-F has not been certified as an Eco-Friendly product. Also, any ink that has Fixer WF-F in it has a pot life of about eight hours. Inks with Fixer WF-N must be cured at 320∘for 3 minutes, but they do not require special handling.
How can I achieve a soft hand feel on the final print?
A smooth print with just enough thickness to be opaque should yield a soft hand feel. If a softer feel is desired, either the printing method or the ink formula can be modified. You can decrease your off-contact and speed up your squeegee movement to reduce the amount of ink being deposited. Also, the ink itself can be modified to be softer by adding up to 3% Softener MG.
How can I achieve a thicker ink deposit?
The easiest way to achieve a thicker deposit is to increase the squeegee angle. Increasing the off-contact of the screen as well as the height of the squeegee yields even more ink deposit. Another option is slowing down the speed of the squeegee. If using an automatic printer, the flood bar can be replaced with another squeegee, which can be lowered to the point where the screen mesh is loaded with ink, creating more deposit when printed. This effect may vary depending on the ink’s viscosity. Screen mesh and emulsion are factors as well. Screen mesh with more open area, and thick emulsion help create a thicker ink deposit.
How can I achieve a thinner ink deposit?
You can achieve a thinner ink deposit by decreasing the squeegee angle and/or increasing the squeegee speed. Decreasing the amount of screen off-contact and squeegee height both help to reduce ink deposit as well. If it is an option, using a screen with a high mesh count and thin emulsion will make a significant difference.
How do I achieve a more opaque print?
A more opaque print can be achieved by increasing the amount of ink deposited, or by using other methods. For example, if printing on a dark garment you can print a white or tinted under base. If the garment is dischargeable you can discharge an under base.Another option is to print, flash, then print the same layer again.
How do I improve the printability of the ink?
To improve the flow of ink through the screen mesh, add the additive Softener MG. Softener MG also helps keep the ink from drying in the screen.
How do I keep the ink from drying in the screen?
To keep the ink from drying in the screen it helps to add the additive, Retarder MG, which also functions to promote the flow of ink through the screen mesh.
What is the difference between Softener MG and Retarder MG?
Functionally they are very similar but their names reveal their primary purpose. Physically, Softener MG is a white, oily paste that dries clear. Retarder MG is a clear, oily, liquid.
How can I eliminate ink from dripping through the screen mesh?
You can prevent ink from dripping through the screen mesh by using a higher mesh screen and/or by reducing the height of the flood bar. Another option is to increase the viscosity by using the additive, Thickener B.
How can I eliminate ink bleeding under the screen while printing?
Ink bleeding could be the result of a number of factors: the screen off-contact may be too low, the squeegee may be too low, the pressure the squeegee exerts may be too high, the ink’s viscosity may be too low, or the screen mesh may be too open.
How do I print on polyester, lycra, or other high-stretch fabric?
If the material is undyed, the stretch series of bases can be printed directly on to highstretch, synthetic material. However, to print on dyed, synthetic fabric, Under Base Blocker 301 must first be printed.
How do I print on tri-blend fabric?
Tri-blend fabric typically requires the use of Under Base Blocker 301 prior to printing any other ink as sublimation is common with tri-blend fabric.
