If you’ve been sending high-volume or specialty print jobs outside the region because your local shop couldn’t handle them, or absorbing outsourcing markups on work that exceeded local capacity, that calculus looks different now.
The RMGT 920PF-8 combines two capabilities that most regional commercial printers don’t run together: convertible perfecting and LED-UV curing. Each one changes how a job is produced. Together, they eliminate multiple steps that have historically added days to a commercial printing timeline.
The press runs sheets up to 25 x 36 inches and prints both sides in a single pass through the convertible perfecting unit. On a conventional press, you run the front, wait for the ink to set, flip and run the back. Any drift between those two passes shows up as misalignment across the finished run. A perfecting configuration eliminates the second pass and that registration risk entirely by imaging both sides simultaneously.
Eight color units — four on each side — means full process color on both sides in one run. For buyers producing full-color, double-sided direct mail, catalogs, or commercial collateral, commercial printing in St. Louis at this spec is a meaningful step up from what most regional shops carry.
LED-UV cures ink on the surface of the sheet as it leaves the press, instantly, with no spray powder and no drying room wait. Conventional presses cure by absorption or heat, which means a finished sheet needs time before it can be handled, trimmed, or finished.
“Jobs that once required two passes and a day of drying now come off the press finished on both sides and ready for the bindery within minutes,” said Jeromy Fritz, President of Presort, Inc. “That is a real advantage for customers working against tight deadlines and mail dates.”
That turnaround compression is a direct result of how the curing chemistry works, not a production estimate. LED-UV also runs cleanly on coated and uncoated papers, synthetic stocks, and specialty substrates that absorb ink unpredictably on conventional presses, producing vivid, high-contrast color and crisp fine detail across the full sheet. It uses substantially less energy than heat-set or traditional UV drying and generates no ozone or heat.
River City Litho is taking print inquiries and shipping LED-UV samples for buyers who want to see what the RMGT 920PF-8 produces before committing a run. Call 800-754-SORT or request a quote online to connect with an account manager and talk through your project specs.
River City Litho operates as part of Presort, Inc., which is one of the few commercial printers in the region that operates as a union shop. That distinction is uncommon in the industry, and it matters to a specific set of buyers.
Presort’s union printing credential comes through its affiliation with the Communications Workers of America Local #14620. Every commercial job that runs through the shop carries that credential. The union bug on a finished piece certifies its origin, and for public-sector clients, labor organizations, and buyers with labor-aligned purchasing guidelines, that certification is often a requirement rather than a preference.
CWA chapters and labor organizations with specific printing, direct mail, and fulfillment needs can find options built around those realities at Presort’s CWA services. Union printing backed by high-volume press capacity is a combination that’s hard to find in this market.
The RMGT 920PF-8 runs inside River City Litho’s production environment, which includes in-house finishing: specialty die cutting and complete booklet finishing with folding, stitching, and trimming. A job doesn’t change hands between press and bindery.
Combined with Presort, Inc.’s mailing and fulfillment services, a project can move from design and printing through finishing, addressing, and delivery to the post office under one roof. Print buyers evaluating which high volume printing company to use for integrated campaigns should ask how many vendors are involved between press and post office. Every handoff is a delay point and a potential markup. Presort eliminates most of them.
The RMGT 920PF-8 is an eight-color sheetfed offset perfecting press with LED-UV curing that runs sheets up to 25 x 36 inches. It prints both sides in a single pass and cures ink instantly, eliminating drying time and allowing immediate finishing. River City Litho, a division of Presort, Inc., installed the press at its St. Louis facility in July 2026.
LED-UV printing cures ink on the surface of the sheet with ultraviolet light as it exits the press rather than through heat or absorption. The result is instant-dry output that can move straight to finishing, consistent color on a wider range of substrates, and substantially lower energy use than conventional UV or heat-set curing.
Yes. Large format printing options are available through Presort’s St. Louis and Cape Girardeau locations. Call 800-754-SORT to discuss substrate, sizing, and turnaround for your project.
The union bug certifies that a finished piece was produced in a union facility. For public-sector clients and organizations with labor-aligned purchasing standards, that’s often a hard requirement. Presort carries the credential through its CWA Local #14620 affiliation, and now has the press capacity to fulfill large runs under that certification.
River City Litho’s RMGT 920PF-8 is in full production. The combination of perfecting, LED-UV curing, in-house finishing, and Presort, Inc.’s mailing services means print buyers have access to a complete production workflow from first proof to post office without multiple vendors or the markups that come with them.
“Our account management team guides every job from quote to delivery, and our quality-first approach means every piece is checked before it leaves our floor,” said Fritz. “This press gives that team a stronger tool to work with, and it gives our customers more options.”
