What's difference between hydrographic dipping film and transfer sticker

Application of hydro dipping film & transfer sticker

Hydrographic ink dipping film is mainly used in water transfer printing process for large-area pattern effect . It is Widely used in metals , ceramics , electronic products printing and so on .

Transfer sticker is also called  water sticker and watercolor printing , a new surface treatment craft , can replace kinds of other printing crafts such as pad printing , silk screen printing, thermal transfer and spraying etc . It is characterized by clear dots and steps , with fine  tone fineness , and its  film surface is soft , performance is stable , transfer sticker also can be used in large-area printing as well as its operation is convenient and simple .

1. Reasons of drawing (knife line) :

  • Scraper has gaps or its quality is poor .
  • Ink particles is large or viscosity is too high .
  • Scraper angle or pressure is unsuitable .
  •  Poorly polished or version roller chrome surface is rough .
  • The plate roller is slightly flat , the ovality is too large , or dynamic balance is not good .

2. Solutions of drawing :

  • Check if there is any gap of scraper , using sandpaper to grind scraper or replace a new one .
  • Filter the ink to reduce larger particles .
  • Polished the surface of plate roller with sandpaper .
  • Check the slightness, ellipticity and dynamic balance of the plate roller .
  • Re-polished or chrome plating again .

3. Net (moire) cause : ink viscosity is not suitable .

Solution : when a solid version and another web version print the netting , it is generally that the ink in the field version is too thin and the ink layer is not thick enough .

4. Rippling occurs : printing ink fluidity is bad .

Solutions :

  • Increase the viscosity of ink  .
  • Increase the printing speed .
  • Correct the printing tension .

5. Same mesh has different color : two-color and multi-color plate net line and net corner are exactly the same  and some dots are completely coincident during printing , some of the dots are staggered , resulting in inconsistent visual coloring . Gray , purple , brown and spot color superimposed of similar meshes are easy to produce same mesh-shaped color shift .

Solution : enhance the overprint accuracy .

6. Dots occur : Due to the fluidity of the ink itself, when the 65-80 mesh is printed , some of dots are connected together , but others are not connected together , causing an uneven printing with serious hue such as dark purple , brown , dark green , deep red , etc .


  • Choose a better ink .
  • Adjust viscosity of ink .
  • Correct angle of scraper or presuress .
  • Enhance the printing speed .

Printing plate quality problem

Printing plate quality problem

Plate roller is important in the process of hydro dipping , many times the plate roller defect can not be adjusted by operation , the following summarizes the common quality problems of the plate and the relative solution .

  1. Blocking (plugging net) Causes :
  • The ink is dry too fast .
  • The mesh pit is too small , causing the ink can not easy to transfer .
  • The inner wall of net pit is not clean and smooth .

Solutions :

  • Change a slow-drying solvent .
  • Increase printing speed .
  • Lower the viscosity of ink .
  • Clean the plate roller after finishing water transfer printing from hydro dipping equipment .
  • Check whether the hair dryer blows the wind onto the plate roller .

2. Corrosion (chrome falling) causes :

  • Plate roller is dirty .
  • Plate is subject to friction or extrusion .

Solutions :

  • Use solvent to clean the surface of plate roller in time after hydro ink dipping .
  • Clear up the plate with clean soft cloth , and do not leave fingermark .
  • Applying low-volatility light oil on the surface of plate roller uniformly , but please do not appying with used engine oil . Of course , special anti-rust oil is better .
  • Use a film (such as a waste film , make sure the ink is facing outwards) , to wrap the oil-coated plate , wrap it in corrugated paper , stand it upside down or use a shelf to keep it in a ventilated , dry and save it in a storehouse avoiding shining directly .
  • Do not arrange the warehouse on the first floor , and keep away from acids , alkalis and other items .
