Sales and service Q: What is the delivery time for a complete system for printing on polyester?
     A: Delivery time is currently: 2 months.

Q: What previous experience does the operator need in order to get the most out of the training course offered by Texdot?
     A: The operator should be used to working with Photoshop or similar software and should also understand color separation for CMYK process color printing. He or she should be experienced in working with technical equipment.

Q: Who is responsible for repairing and maintaining the system?
     A: After training at Texdot, the operator him/herself will be able to carry out normal maintenance of the system. The operator will also be able to carry out certain repairs. If there is a service agreement, Texdot can provide service engineers for more difficult problems.

Q: What kind of service contract is offered and how much does it cost?
     A: The cost of a service contract depends on the degree of system availability required by the customer.

Q: Can a system be installed and commissioned by a Texdot-trained operator and our own technicians?
     A: As long as the customer has carried out the required installations for the supply of electricity, water and ventilation plus compressed air, there should not be any problem.
Technical questions Q: How long can a printer head be expected to last?
     A: The lifetime of a printer head depends a great deal on the characteristics of the ink. When using inks for polyester, one should expect a lifetime of approximately 12 months on a machine running on 8-hour shifts.

Q: Does the inking system have to be cleaned out when printing is finished?
     A: This is not necessary if the machine is idle for less than 24 hours.

Q: Are there special environmental requirements for the premises where the machine is to be operated?
     A: The system is designed for a normal industrial environment.

Q: How is the fabric dried in the machine?
     A: The machine has an integrated drying system with circulating hot air.

Q: Can the machine be used on small premises with a normal ventilation system?
     A: You need to install filters in your ventilation system that connect to the printer. The filter must be able to handle air with water and ink content. The ventilation tubes should have a minimum of 100 mm in diameter. The maximum under-pressure is 5mBar.

Q: How are waste liquids removed from the machine?
     A: All liquids required for cleaning the machine are conducted to an outlet where they can be collected. Water is used together with a mild water-based detergent, when cleaning the ink system.

Q: What consumables are needed for the functioning of the machine?
     A: Apart from inks and textiles, cleaning fluid (water) for the ink-system and filters for the inks.

Q: Can the textiles affect the reliable operation of the machine?
     A: Textiles with a lot of loose fibers on the surface can cause more frequent down-time during printing for cleaning the bottom surface of the inkjet heads .

Q: How often does the machine need cleaning to avoid ink marking problems?
     A: A regular general cleaning of the printer is needed to avoid dust and ink waste leaving markings on the fabric.
Inks Q: Are there inks for different materials?
     A: At present, Texdot can supply inks only for Polyester.

Q: Can inks for Polyester be used on other materials?
     A: Inks for Polyester can also be used on Triacetate.

Q: Are the inks solvent-based?
     A: Texdot supplies only water-based inks.

Q: What colors can Texdot supply?
     A: The standard Texink colors are Cyan, Light Cyan, Magenta, Light Magenta, Yellow, Black.

Q: Are the inks weatherproof and light-fast?
     A: This type of inking produces first class qualities of weatherproofing and light-fastness as well as mechanical wear resistance. Level 7 on a Blue Wool Reference 8-level scale.

Q: How are the inks for polyester treated afterwards?
     A: The Texdot® product program includes equipment for fixing inks on polyester during production. The fixing of polyester involves a dry heat treatment that takes about 5 minutes.

Q: Must fixing be performed directly after printing?
     A: No. Unfixed polyester can be stored and fixed later.

Q: Is it possible to use inks from other manufacturers?
     A: The inks are integrated into the system. Texdot advises against experiments with inks not supplied by Texdot®.

Q: Does Texdot have the resources for developing inks for other materials?
     A: This is possible as there is an ongoing in-house development and production of inks at Texdot.

Q: Can ink dry and clog the print head?
     A: This is not a serious problem since the polyester inks do not contain binding agents. This means that when you stop production for up to 24 hours there is no need to take measures to prevent drying in the printer head's ink-jet nozzle. If this should occur nevertheless, the printer head can be replaced without any tools. Also, the design of the printer head allows it to be washed in ordinary tap water. In cases when tap water cleaning is not enough the cleaning can be performed in an ultrasonic cleaner, and this usually solves this type of problem.

Q: What is the volume of an ink container?
     A: The volume of an ink container is either one or five liters.
Textile materials Q: What materials can the JP200cvt print on?
     A: JP200cvt can print on all materials, but there is only ink developed for Polyester fabric at present.

Q: Are specially treated textiles required?
     A: No. You can use any polyester textile.

Q: Can different widths of textile be used?
     A: Yes. Up to 2100 mm.

Q: Is it possible to print on mixed-fiber materials?
     A: Yes, but even small amounts of cotton (for example) mixed with polyester diminish the luster of the colors.

Q: Can elasticized textiles be printed on?
     A: The JP200cvt is designed so that the inks penetrate the textile and therefore the textile is not supported by the feed system. This might create problems, so we recommend that the particular textile is tested on the machine first.

Q: Is there a problem with the buildup of electrostatic charge in the textile?
     A: JP200cvt is fitted with ionizing units which solve this problem.

Q: Does the textile's weight per square meter affect the printing speed?
     A: No. By changing parameter settings in the software, the droplet volume will be adapted to the medium used.

Q: How is the textile affected when the inks are fixed?
     A: The textile width may shrink, usually by between 1% and 3%

Q: Can Texdot recommend suitable textiles for the JP200cvt?
     A: Texdot has a number of different textile qualities in knitted and woven polyester. All tested and certified together with the ink and printer.

Q: Is it possible to arrange a trial printing on the textile which our company uses at present?
     A: Of course Texdot can carry out a trial printing for you.

Q: Can Texdot recommend textile materials for such applications as flags and large pictures?
     A: Texdot has textiles which are suitable for various applications and has developed a method for sewing large pictures together so as to ensure good pattern alignment and strength.

Q: What is the largest size of textile roll that can be used in the machine?
     A: The maximum diameter is 300 mm.

Q: Does the printed medium need any other after-treatment?
     A: When the printed textile is to be used outdoors, we recommend that the textile be washed.

Q: Can the textile affect the appearance of the printed image?
     A: Certain qualities are more suitable for large pictures where a greater viewing distance is involved.
