Q: oily or damp

Reasons Baking dried patterns or pasted and transferred patterns become oily and damp Solutions It belongs to the phenomenon that the glue is not baked thoroughly, the water and glycerin in the ink cannot be thoroughly baked and then reversed. Generally speaking, single sheet operating version with 120 degrees low temperature for a long time through it best. As powder is limited by the length of the powder machine, so we can try to raise the connected board appropriate high temperature to make the water and glycerin evaporation in advance might also help

Q: Flaking powder

Reasons The blank place powder around the pattern sticks the coating after heat transfer printing Solutions May due to the heat transfer printing pressure is too high, which makes the film ink absorbing layer damage peeling or fabric surface size easy to stick the coating. Generally, as long as the temperature and pressing time can meet the requirements of sticking firmly, it can be easily solved when adjust the pressure as small as possible down

Q: Ink Contam

Reasons 1.The damper in the ink supply system is damaged, leaking air, or has abnormal ink return, causing ink back - flow and mixing due to negative air pressure. 2.Improper cleaning of the print head leads to bubbles from cleaning liquid affecting ink flow. 3.The wiper blade is aged, and the ink - suction function of the capping station declines. Solutions 1.Check and repair or replace the damaged damper. 2.Standardize the print head cleaning process and avoid long - term soaking. 3.Replace aged components in time, clean dirty blades regularly, and adjust nozzle positions if necessary.

Q: Poor pattern clarity

Reasons 1.Poor quality in screen - plate making for printing, such as issues with pattern effect, screen tension, and plate - exposing process. 2.Uneven ink - scraping pressure during printing. 3.Inappropriate ink viscosity. 4.The printing substrate is too rough. Solutions 1.Improve screen - plate making standards, ensure proper tension and pattern effect, and optimize the plate - exposing process. 2.Adjust the ink - scraping pressure to make it even. 3.Adjust the ink viscosity according to actual conditions. 4.Select a suitable substrate or pre - treat rough substrates.

Q: Color Migration & Discolor

Reasons 1.Insufficient curing temperature, leading to insufficient ink layer curing. 2.The printing substrate contains disperse dyes, and the dyes sublime during heat treatment. 3.Using inks with poor migration resistance, such as purple, peach red, and fluorescent colors. 4.Excessively high ink curing temperature. Solutions 1.Ensure sufficient curing temperature and time. 2.Know the dye components of the substrate, avoid using substrates with disperse dyes or pre - treat them. 3.Select ink colors carefully and control the temperature during high - temperature curing.

Q: Weak Adhesion & Fading

Reasons 1.Insufficient curing temperature, resulting in incomplete ink curing. 2.Insufficient power of the equipment, causing inconsistent curing degrees between the surface and bottom of the ink layer. 3.The printing material is not suitable for DTF ink. Solutions 1.Accurately set and control the curing temperature and time. 2.Check the equipment power and repair or replace it if necessary. 3.Select a printing material compatible with DTF ink.

Question 1

oily or damp

Accepted Answer

Reasons

Baking dried patterns or pasted and transferred patterns become oily and damp

Solutions

It belongs to the phenomenon that the glue is not baked thoroughly, the water and glycerin in the ink cannot be thoroughly baked and then reversed. Generally speaking, single sheet operating version with 120 degrees low temperature for a long time through it best. As powder is limited by the length of the powder machine, so we can try to raise the connected board appropriate high temperature to make the water and glycerin evaporation in advance might also help

Question 2

Flaking powder

Accepted Answer

Reasons

The blank place powder around the pattern sticks the coating after heat transfer printing

Solutions

May due to the heat transfer printing pressure is too high, which makes the film ink absorbing layer damage peeling or fabric surface size easy to stick the coating. Generally, as long as the temperature and pressing time can meet the requirements of sticking firmly, it can be easily solved when adjust the pressure as small as possible down

Question 3

Ink flow

Accepted Answer

Reasons

1.Ink is prone to flow in areas with powder impurities or crush wounds.
2.The heating board fails to operate properly after printing.

Solutions

If ink flow is caused by poor absorption:
1.Reduce the proportion of white ink setting and moderately cut down the quantity of white ink.

2.Increase the temperature of the printer heating board to improve the pass - rate.
3.Utilize board heating to activate the ink, thereby reducing the ink flow phenomenon.

Question 4
