Diffraction gratings in sol–gel films by direct contact printing using a UV-mercury lamp

We report on the fabrication of diffraction gratings in photosensitive sol–gel thin films by direct contact printing using a UV-mercury lamp. Titanium amplitude masks were used to replicate diffraction gratings into photosensitive sol–gel films by contact printing with an incoherent UV-light source. Gratings with 1-mm period were fabricated in sol–gel films. The diffraction efficiencies of each...

Lightfastness and Weatherfastness of Overprint Pattern Obtained on Polymer Substrates

The flexographic printing is the fastest growing printing technique nowadays [1]. The principal advantages of flexography are reflected in the markets where it is most often used. The advantages of flexographic printing are low cost and short circle time, precise ink transfer with minimum on-press adjustments, and ability to print one layer and laminate another layer over it in a continuous pro...

Concave Microlens Array Mold Fabrication in Photoresist Using UV Proximity Printing

This paper presents a simple and effective method to fabricate a polydimethyl-siloxane (PDMS) microlens array with a high fill factor, which utilizes the UV proximity printing and photoresist replication methods. The concave microlens array mold was made using a printing gap in lithography process, which utilizes optical diffraction of UV light to deflect away from the aperture edges and produc...

Synthesis and characterization of novel dual UV/thermal curable epoxy rosinate

Rosin has a comprehensive application in adhesives, printing inks, protective coatings, rubbers and pharmaceutical. In this work, novel dual UV/thermal curable epoxy rosinate was synthesized by esterification reaction between epoxy resin and purified rosin. This product was evaluated by FT-IR spectroscopy techniques and acid number. UV curable resin was formulated for UV curing ability by benzo...
