Printing techniques |
|
 |
|
Tyvek is printable using all traditional techniques: offset, flexo and screenprinting. |
|
|
Tyvek can be used for most digital printing techniques: inkjet, thermal transfer, UV-curable and HP Indigo. |
|
|
Hot laser and photocopying is not possible. |
|
|
|
|
Converting |
|
|
|
Tyvek can be punched, die-cut, stapled, sewn and glued. |

Five tips for offset printing with Tyvek® |
|
|
|
It is important to use low solvent content offset inks that are recommended for Tyvek®. The inks should contain less than 3% volatile solvent, since hydrocarbon solvents found in most offset inks will swell and distort Tyvek®. |
|
|
Usually Tyvek® will require about 0.08 - 0.10 mm additional impression compared to a sheet of paper of equivalent thickness, because it is more compressible. |
|
|
Tyvek® does not absorb water as readily as paper, for this reason, the press should be run with less dampening solution. |
|
|
Print with the minimum ink film thickness. This will minimise dot distortion, sheet distortion and
the appearance of fibre swirl and will also reduce ink drying time. |
|
|
It is recommended that 4 colour work is conducted only on 4 colour machines, because Tyvek® is subject to stretching. |
|
|
|

|
Five tips for flexo printing with Tyvek® |
|
|
|
Low temperature drying is the key to printing Tyvek® by flexography. |
|
|
It is important to use flexo inks that are recommended for Tyvek®. Inks containing
less than 3% residual solvents should be used. |
|
|
Many different flexo inks are suitable for Tyvek®, like volatile solvent, waterbased and UV-curing inks, in each case, the volume of ink on Anilox roll needs to be adapted to type of Tyvek® and to print layout. |
|
|
Web temperature should be kept below 80ºC and tension below 1.4 N/cm of width. |
|
|
To help overcome the inherent thickness variation of Tyvek®, mount plates with 0.38 - 0.55 mm of sticky back closed cell foam tape. |
|
|
|
For more information on flexo printing with Tyvek®, please refer to page 8 of the Tyvek® Handbook. |
|
|
|
|
Five tips for screen printing with Tyvek® |
|
|
|
Tyvek® can be printed on hand, automatic and rotary screen presses in sheet and roll form for signs, banners and other decorative uses. |
|
|
When high velocity hot air is used instead of room temperature drying, the sheet temperature should be kept below 80ºC (175ºF) with tension below 1.4N/cm to avoid mis-registration in multi-color web printing. |
|
|
Use recommended inks for screenprinting with Tyvek®. |
|
|
Some solvents used in screen inks can cause undesirable swelling, distortion and mis-registration. Poster paints and enamels containing hydrocarbon solvents are not recommended for screen printing Tyvek®. |
|
|
When using UV-cured screen inks, cooling is required to prevent sheet distortion or shrinking due to the heat generated within the ink when curing heavy coverage of dark solids. |
|
|
|
