This is one of the recent developments in printing which gives thick prints on the surface of garments.Achieved by either giving more number of coats or by using thickener indirect films used for making the screens. This type of printing apply by screen. Rubber or plastic sold is used as a paste. Screen applies many times on a same design. If it may be thick around 5-6mm then apply high density sticker. High Density is a popular special effect that rises straight up off the shirt and has a hard rubbery feel with sharp edges. A High density print has slight glossy finish.

High density printing

  1. 1. High density printing
  2. 2. High Density Printing  High- Density Printing the process of printing a specially formulated ink through a very thick stencil to achieve a raised, glossy smooth print with very sharp edges.  High density inks allows you to achieve a three-dimensional effect with sharp, well defined outlines.  The process is very slow but the end product is unique.

  4. 4. High-Density Printing Process Flow Chart Fabric/ Garments Pre-Treatment Prepare High-density paste (100%) Screen Table/ Machine preparation Fabric Plaited on the table High-density Paste apply by screen Curing at 160 °C (Belt speed 3 min/min) Delivery
  5. 5. High-Density Printing Technique • HD or High Density Printing utilizes advanced technique from an experience screen printer to achieve a unique 2D style finish that is raised from the T-shirt. • Correct HD printing isn't just building layers upon layers using normal plastisol ink through a standard coated screen. To achieve the best result, it all comes down to the screen itself. • We coat the screen multiple times until we are happy with the thickness of the outside face of the screen, we then use a special film that works with this thicker emulsion. • Once our screen is complete, we mix a specially formulated HD ink which will slightly raise but still remain sharp. This process is fairly complex and time consuming but the results speak for themselves.

  7. 7. The Inks • There are three general types of textile inks (or pastes, as we referred to them in Printing ): 1. Solvent-based inks (Traditional) 2. Water-based inks 3. Plastisol inks (recommended to use in High density print)
  8. 8. High Density Ink • High Density is a popular special effect ink that when printed, rises straight up off the shirt and has a hard rubbery feel with sharp edges. A High density print has slight glossy finish. • Suede is a milky coloured additive that is added to Plastisol. With suede additive you can make any colour of Plastisol have ‘suede’ feel. • Generally 50% suede additive to your normal Plastisol.Suede is a special effect ink similar to high density ink except with soft leather like feel.[18] Suede ink can be either printed high for a 3-D effect or printed normally for a more subtle felt like feel.
  9. 9. A finished sueade print has a matte finish and is very soft to the touch.High Density and Suede are clear bases that can be added to any print color. (example blue-"High Density" grey "Suede" Suede is a special effect ink similar to high density ink except with a soft leather like feel. Suede ink can be either printed high for a 3-D effect or printed normally for a more subtle felt like feel. A finished sueade print has a matte finish and is very soft to the touch. High Density and Suede are clear bases that can be added to any print color. (example blue-"High Density" grey "Suede" Suede ink was derived from puff ink. The process for printing is similar, but suede ink results with with a raised fuzzy nap reminiscent of suede leather Suede leather is made from the underside of the skin, primarily lamb, although goat, pig, calf and deer are commonly used
  10. 10. Plastisol inks  Plastisol inks are widely used in garment printing.  They are easy to print, do not dry in the screen, can be very opaque on dark garments, and will adhere to most textiles.  They are composed primarily of two ingredients, PVC resin (a white powder) and plasticizer (a thick, clear liquid).  Plastisol inks have one outstanding characteristic, they must be heated to dry. They will not dry, or cure, at normal temperatures. For a complete cure, they must reach 290-330º F (143-166º C).  Plastisol inks do not color the fibers like a dye. Instead the ink wraps around the fibers and makes a mechanical bond with the fabric. For this reason, they will not adhere to non-porous substrates such as plastic, metal, and glass.  Health, Safety and Environmental friendly.
  11. 11. • Pantone Approved - Color Matching System : • Plastisol Ink Mixing System is the next generation of inks for mixing colors. The PIM system contains 10 primary High Opacity colors and uses only 6 Fluorescent. All colors have wet on wet properties. Recipe book is available for creating shades. With the uses of enhancer additives special effects become simple. Whether matching Pantone or a buyer’s special color, this system will make matching simple. PIM System will reduce overall cost. The easy of printing will increase production speeds. • Application and Substrate: Mixing colors can be printed directly on cotton, cotton/polyester or polyester fabrics. • Stencil: Direct, Indirect or Capillary Films NB: When printing on nylon fabric use Long Life Bonding Agent (add 10 to 15% by weight).
  12. 12.  High Density Inks work best with solid, bold graphic areas such as text or symbols and logos.  High Density Inks cannot be used for halftone images or graphics with fine detail.
  13. 13. Screen Printing • A process, where ink is mechanically applied to a substrate with the use of a screen and squeegee.
  14. 14. Mesh count  The mesh count is the number of threads per inch (tpi) used to weave the mesh.  Typical mesh counts for screen printing range from 85 tpi to 355 tpi.  The high mesh counts, have a very small thread diameter and less open area.  Prints require more fineness should be use finer mesh count. Hi density printing ink Mesh count 1. Solvnt/Water base (1st & 2nd times) Overprint (3rd to 6th times) 2. Plastisol 80 –110 110 –175 125–305

  17. 17. High Density v/s Rubber Puff Printing High density screen printing at first glance seems to be some sort of high-quality puff print. Actually, the high density inks are not puff inks at all. They are a high viscosity ink designed to easily flow through your screen mesh while holding a very sharp edge with durability fasteners towards World Standards.
