Print quality is enhanced using a technologically advanced inline drying system, which allows for rapid, effective drying of water-based inks and varnish. This is especially important where colors touch or overlap. Designs with heavily printed areas and tightly registered graphics will look bright and crisp upon completion.

The machine also features sheet cleaning and dust control, both of which help to minimize print defects caused by dust and paper debris.

We understand the need for accurate color matching when it comes to your brand identity. At Acme, we maintain an on-site ink blending station that allows us to create custom colors that match your requirements. Using Color ConneXion® color management software, Acme’s Ink Specialists will assist you in managing your colors from design concept to production. No need to special order custom inks when we can mix them on demand.

Layout of graphics from the top to bottom of the corrugated sheet during printing and converting is critical. Standard registration crosshairs are used to align print elements on each side of the sheet. In addition, the cutting die is precisely registered to the print elements and corresponding crosshairs mark its position.

This also provides a simple reference for position of print elements from top to bottom. These tools ensure that your box is printed and cut to your specifications.


What is the difference between I/O Specialty Printing and 2-sided printing?

They are the same thing. Some people refer to the process of printing on both sides of a sheet of corrugated as I/O or Inside/Outside printing, others refer to it as 2-sided. We refer to it as I/O Specialty Printing for two reasons.

A) It’s not something that all box makers can do in a single pass and requires a specially configured machine to do it.

B) It offers a special advantage to our customers that sets them apart from their competition and communicates their message.

How many colors can I print on my box?

We can print up to 3 colors on the outside of the box and 2 colors on the inside. If varnish is desired on either side, a print unit would be used for that purpose and counts as a color.

What types of boxes can be produced with two-sided print?

While the machine printing the boxes is configured to produce die-cut boxes, any box type can be produced (within the size limitations of the machine). Conventional boxes with glue joints (RSC) will require gluing to be completed as a second process.

What about boxes with glue?

A standard RSC or HSC style box would require a second process for gluing which would take place after printing. If the piece is to be glued by the user, standard gluing equipment should work the same way. If there is heavy print coverage in areas to be glued, color should be knocked out to allow for optimal bond.

How can I be sure that my brand colors match perfectly?

Acme has an on-site ink blending station where custom or match colors can be accurately blended with the assistance of a computer.
In addition, a spectrophotometer will read the color for accuracy and provide guidance for any adjustments that may be required. So we can match your brand colors perfectly both inside and out!

Does I/O Specialty Printing require additional turnaround time for production?

The production side of the 2-sided printing process itself does not require any notable extra time. However, preparation and approval of artwork, making print plates, and fabricating the cutting die can add up-front time prior to production.
