ABSTRACT :
Printing is done for various aspects such as
for decorating purpose, information shearing
through magazine, news paper, books, on textile
etc. The design or text is printed on cloth or
paper or wood. In printing there is problem to
cure (dry) the ink after print. If it is not cure
as early then there is possibility to sprayed the
ink. The aim of this project is to control various
aspects of curing such as level of ink, temp of
lamp, moisture/humidity of ink and speed of fan
by using PLC & Microcontroller.
Ink is spared over it which is needed to cure
or dry. To fulfill this requirement a continuous
monitoring and controlling is required.
Monitoring is achieved by using Microcontroller.
Microcontrollertranslate the data on
PC, all required levels for curing is set by
microcontroller. Microcontroller set the level
of ink, temperature level of UV lamp, moisture
level of ink and speed of blowers.
I. INTRODUCTION
The curing of various surface coatings with
light can be traced back many centuries to the
time the ancient Egyptians cured resin soaked
mummy wrappings by sunlight. Since then,
innumerable photochemical reactions have been
discovered. However, there was no commercial
photo curing process until the 1960’s. Finally,
in the late 1970’s, rapid advances in technology
made UV curing inks and coatings commercially
viable.
