Uneven colour: Always make sure that the colour is the same on both sides of the sheet by rolling the sheet up so that you can look at opposite edges of the sheet side by side.
Ghosts: These are either images formed in areas where they should not appear, or formation of lighter areas where there should be even inking.
Hickies (aka Fish-Eyes): Non-inked circles created by lint on the plate or blanket. They are generally something that can be cleaned up when appearing on several sheets in a row. However, chances are you will never be able to eliminate every single hickie, especially if you have large solids in your printing piece and have to print thousands of sheets.
Picking: These are the non-inked areas that look like snow created in areas where the ink and some of the paper has been lifted off the sheet when the ink is too tacky. Picking can occur due to a paper related problem.
Muddy or Uneven Screens : These occur as a result of dot gain. In the worst case scenario caused by a muddy or uneven screen, you may need to remake a plate using a coarser screen. However, some dot gain can be alleviated by running the ink a little lighter and by ensuring that the gradients on your piece, if any, look even.
Offsetting: This is the appearance created on the back of a sheet by an image present on the sheet touching it. Offsetting happens as a result of too much ink insufficient driers in the ink or trimming of the job done when the ink is too wet.
Today's lithographic offset printing industry is a dynamic technology-driven service sector in the midst of widespread technological changes. These changes are driving quality up whilst reducing process time. This is highly beneficial to our customers and Erawan embraces technology as a means of providing a better service to our customers.
Whilst the printing process itself is important, most of our customers have very practical goals as far as their print jobs are concerned, namely to produce high quality documents, on time, and at a competitive cost.
At Erawan, we strive to exceed our clients' expectations on their print work. Our goals are clearly defined as part of our offset printing pledge:
