1. 1. 1. 1. APPLICATION APPLICATION APPLICATION APPLICATION FIELDS: FIELDS: FIELDS: FIELDS:
Universal UV screen printing ink in a thixotropic formulation for
the printing on blow moulded objects within the packaging
industry. Suitable for pre-treated substrates made of polyethylene
(PE), polypropylene (PP), PVC and other plastic types as well as
for printing on paper and cardboard.
Substrates may differ in their chemical structure or
method of manufacture. A test for suitability must always
be carried out before printing. Antistatic, Mould Release
Agents and Slip Additives may have negative effects on
adhesion, and should be detected and removed prior to
printing.
2. 2. 2. 2. CHARACTERISTICS: CHARACTERISTICS: CHARACTERISTICS: CHARACTERISTICS:
This high gloss UV ink series is very reactive in nature,
assuring good curing and adhesion even when printing at
high machine speeds.
The inks of the 920 UV series are constitutionally free from
toxic elements and solvents. The raw materials used meet
with the limits stipulated by the EEC regulation EN 71
(Safety of Toys), part 3 (Migration of Certain Elements) of
December 1994. The inks of this series will exhibit good
solvent and water resistance after 12 hours. Due to their
viscosity adjustment, which is higher compared to the 985
UV series, this UV ink series is also suitable for application
under extreme climatic conditions (temperature > 28 ° C).

In the case of particularly high resistance requirements,
the addition of adhesion modifier is recommended. However
the addition of adhesion modifier to UV curable ink
will lead to a processing time (potlife) of 4-8 hours at 21 ° C
depending on the colour shade. Higher processing temperatures
will result in a shorter potlife.
Overprinting must take place within 12 hours at 21 ° C in
case an adhesion modifier is added.

6.1 6.1 6.1 6.1 Pre-treatment: Pre-treatment: Pre-treatment: Pre-treatment:
Pre-treatment of polyolefines (PE/PP) must be performed
by Flame Treatment or CORONA-discharge in order to
insure the adhesion of the UV screen printing ink to the
substrate. In case of PE, surface tension needs to be at
least 42 mN/m (Dynes/cm), in case of PP at least 52 mN/m
(Dynes/cm).
6.2 6.2 6.2 6.2 Stencils Stencils Stencils Stencils / / / / Printing Printing Printing Printing Equipment: Equipment: Equipment: Equipment:
Screen printing meshes between 140-34 threads/cm and
200-34 threads/cm are suitable for printing with UV inks.
The colour mixing formulations are based on a 165-34
threads/cm mesh. However, test prints and approval of the
colour are generally recommended for the respective print
jobs. The 920 UV series can be used with all screen printing
machines with screen printing stencils currently used
for industrial applications. Any acrylic acid ester resistant
squeegee material may be used.
6.3 6.3 6.3 6.3 Curing Curing Curing Curing Conditions: Conditions: Conditions: Conditions:
The varying UV absorption of the inpidual colours results
in a range of curing properties depending on colour and
opacity. All colours of the 920 UV series can be cured by
the use of medium pressure mercury vapour lamps (at
least 160 W/cm). The optimum energy output is 250 - 300
Millijoule/cm2. UV curing is followed by a 12 hour post-cure
phase after which the ink film is fully cured and has its final
properties.
5.2 附着力促进剂
如果需要特别高的耐受性要求，推荐使用附着力促进剂。然
而，在 UV 固化油墨中添加附着力促进剂，将导致 21 度下的
施工期约为 4-8 小时，根据颜色的不同而不同。高施工温度
将导致短施工期。
如果添加附着力促进剂时， 21 度下必须在 12 小时内重复印
刷。

5.3 流平剂
油墨表面的流平性可以用流平剂来优化。

6. 工艺要求
6.1 预处理
必须使用火焰处理或电晕处理进行聚烯烃（ PE/PP ）的预处
理，以保证移印油墨对基材的附着力。对 PE 而言，表面张
力至少达到 42nM/m （达因 / 厘米），对 PP 而言，至少达到
52 nM/m （达因 / 厘米）。
6.2 印版 / 印刷设备
丝网目数介于 140-34 线 / 厘米和 200-34 线 / 厘米适用于 UV
印刷油墨。混色配方基于目数为 165-34 线 / 厘米。然而，通
常推荐对不同的印刷工作须做印刷试验和颜色确认。 920UV
系列可用于目前工业应用中使用的印版和所有的丝印机器。
可以使用任何类型的耐丙烯酸酯的刮板材料。
6.3 固化条件
各种颜色对 UV 吸收的不同，导致了由颜色和遮盖力决定的
固化特性。 920UV 系列所有的颜色可以使用中等压力的汞蒸
汽灯（ 160W/ 厘米）固化。最佳能量输出为 250-300 毫焦耳 /
平方厘米。 UV 固化完成后，应该有 12 小时的养成期，以使
油墨完全固化，并达到最终特性。Technical Data Sheet

However, it must be noted, that low radiation intensity,
excessive machine speeds or excessive film thickness can
have a negative influence on the curing properties and
adhesion.
Un-cured prints are considered a hazardous waste. Therefore,
it is recommended to cure misprints under the UV
lamp as a matter of principle. After curing, spoilage can be
disposed by conventional methods and may be incinerated
without causing any difficulties.

Screens and squeegees as well as other working materials can be
cleaned with the RUCO screen cleaner 32 335. If cleaning is not
performed by fully automatic cleaning equipment, protective
gloves must be worn. Cleaning liquids that are contaminated with
UV products should not be used for the washing of working
materials that were used with conventional screen printing inks.
Solvents that contain UV residue are not suitable for reclamation
and must be treated as a separate waste.
