Printing with Genesta inks

Genesta inks have been developed by Epson in collaboration with For.Tex specifically for the Monna Lisa series, to allow precision, reliability and durability of fabric prints. Genesta inks - Acid, Reactive, Disperse and Pigment - provide the highest quality on any fabric. The exclusive Monna Lisa ink management system limits waste and the suction system is designed to permit the use of degassed vacuum bags.

A thorough activity of Research & Development continues to expand the range of inks or colours, and to improve printing quality.

Acid inks
GENESTA® AC

Genesta AC inks may be used for printing on properly prepared silk, wool and PA fabrics using the Monna Lisa series printer.

Drying is easy and the dried fabrics can be stored before steaming, which is performed using saturated steam at 102°C for 30 minutes (40 minutes for wool).

In order to eliminate the unfixed ink and the preparation, specific washing treatments are performed according to the type of the printed fabric.

Genesta AC inks are available in the following types:

Reactive inks
GENESTA® RE-N

Genesta RE-N inks may be used for printing on properly prepared cotton, viscose, linen and other cellulose fabrics, silk and wool using the Monna Lisa series printer.

Drying is easy and the dried fabrics can be stored before steaming, which is performed within 24 hours after printing with saturated steam at 102°C for 12-15 minutes in case of cellulose fibres, 20 minutes for silk and 30 minutes for wool.

Special care must be taken to ensure the steam has the proper characteristics: it must be free of any nitrogenous compounds which are often used as additives in boilers or may remain as residues of previous steaming of fabrics printed with acid inks.

In order to eliminate the unfixed ink and the preparation, specific washing treatments are performed according to the type of the printed fabric.

Genesta RE-N inks are available in the following types:

Disperse inks
GENESTA® DS

Genesta DS inks may be used for printing on properly prepared PES fabrics using the Monna Lisa series printer.

Drying is a bit more difficult than the other inks because polyester has low absorption capability. So, we suggest using a paper sheet to avoid back staining.

The dried fabrics can be stored before fixation, that can be done as follows:

  • using heated steam at 170°C for 10 minutes (suggested method)
  • using air at 180°C for 2 minutes

In order to eliminate the unfixed ink and the preparation, specific washing treatments are performed.

Genesta DS inks are available in the following types:

Pigment inks
GENESTA® PG-2

Genesta PG-2 inks may be used for printing on properly prepared cotton, viscose, linen, other cellulose and their blends with PES and PA fibres using the Monna Lisa series printer. The best results, especially for colour yield and brilliancy, are obtained by printing on fabrics pre-treated with Pregen PG or PCC.

Post-print drying must be calibrated to properly initiate the resin cross-linkage process and consequently the temperature on the fabric must be at 150°C for at least 1 minute. In fact, the Genesta PG-2 inks contain a small amount of binder which is necessary to make the pigment resistant to wetting but not to washing with detergents.

Colour fastness is then ensured by post-treating the fabric with special products. After applying the post-treatment, the resin must be baked again at 160°C for 2 minutes.

Genesta PG-2 inks are available in the following types:

Digital textile printing
is easy on the environment

There is a consensus that inkjet printing is the future of textile printing.
Advantages such as lower production costs and the possibility to customise short runs are undeniable. But there’s more. The Total Solution system offers printing companies and other operators in the textile production chain considerable benefits in terms of environmental impact and compliance with the laws, regulations, certifications and restrictive specifications produced by customers and brands in the fashion industry.

A study comparing a production cycle using Monna Lisa series and one using a rotary press, carried out at a printing company equipped with both kinds of technology installed, shows the advantages of inkjet technology in terms of carbon footprint and water consumption. In particular, the reduction in water consumption (-27%) has two important environmental benefits: reduction in the volume of wastewater sent to treatment plants and reduction in the amount of energy needed to heat process

water. In terms of carbon footprint, the conventional rotary system generates 139.56 kg of CO2eq, while the digital system produces 85.66 kg of CO2eq.*

Our environmental certifications

 
 

All types of Genesta inks have been granted the ECO PASSPORT certification by OEKO-TEX®, assurance that they meet the strict human-ecological standards for chemicals.

 
 

The bluesign® system is the solution for a sustainable textile production. It ensures that the final textile product meets very stringent consumer safety requirements worldwide and also provides confidence to the consumer to acquire a sustainable product.

Global Organic
Textile Standard

Reactive Genesta inks have been approved by ECOCERT, certifier for GOTS (Global Organic Textile Standard). GOTS is the worldwide leading textile processing standard for organic fibres, including ecological and social criteria, backed up by independent certification of the entire textile supply chain.
