 When Lichtenstein made his transition to comic @-@ based work , he began to mimic the style while adapting the subject matter . He applied simplified color schemes and commercial printing @-@ like techniques . The style he adopted was " simple , well @-@ framed images comprised of solid fields of bold color often bounded by thick , stark border lines . " The borrowed technique was " representing tonal variations with patterns of colored circles that imitated the half @-@ tone screens of Ben Day dots used in newspaper printing " . PBS asserts that this is an adaptation of the ligne claire style associated with Hergé . Lichtenstein once said of his technique : " I take a cliche and try to organize its forms to make it monumental . "
