Introduction
Running a short-run envelope job on an offset press means plates, chemicals, and skilled operators, just to print a few thousand pieces. Toner systems are more flexible but choke on speed and cost once volume climbs.
Many commercial printers and mailing operations know this problem well: setup time eats into profit, and any request for personalized, full-color envelopes turns into a scheduling headache.
The industry has been moving away from these constraints. In a 2025 survey of in-plant print operations, PRINTING United Alliance found that printers added twice as many inkjet envelope presses as toner envelope presses over the prior two years. Digital inkjet is no longer a niche alternative. It is the equipment printers are actually buying.
iJetColor has been part of that shift, with more than 2,500 machines deployed to over 1,500 customers nationwide. This guide breaks down what inkjet envelope printers are, walks through iJetColor's full lineup, and helps you match a model to your volume and budget.
Key Takeaways
- Thermal and piezo inkjet deliver full-color, full-bleed printing with near-zero setup waste
- iJetColor models span 1,500–20,000+ envelopes/hour across benchtop, console, and industrial tiers
- Switching from offset or toner often pays back in as little as 12 months via lower cost-per-piece
- HP 990 pigment inks are RISE-certified per ISO 11798 for light, water, and abrasion resistance
- The 1175 Pro won 2020 Printed United Alliance Product of the Year in the digital press category
What Is an Inkjet Envelope Printer?
Inkjet printing fires microscopic droplets of ink through a nozzle array to build an image directly on the page. No plates, no dies, no chemistry. Two engineering approaches dominate commercial envelope presses.
Thermal vs. Piezo Print Engines
- Thermal inkjet (HP PageWide): A tiny heating element vaporizes ink inside the nozzle, creating a bubble that forces a droplet out. This powers HP's FI-1000 print engine, used across most of the iJetColor lineup.
- Piezo drop-on-demand (Memjet): An electromechanical element flexes to change the ink chamber's volume, pushing out a droplet without heat. iJetColor's Press and NXT models run on Memjet engines.
Both approaches solve the same problem differently: put ink exactly where it belongs, at speed, without a plate.
Built to Handle Flaps, Seams, and Varying Thickness
A document printer only has to move flat paper in a straight line. An envelope printer has to manage a seam down the middle, a flap that folds unevenly, and stock ranging from a lightweight #10 to a padded mailer. That's why each iJetColor press is built around a dedicated feeding and alignment system, not a printhead bolted onto a generic paper path.
The 1175 Pro and PXG use "Straight Shooter Technology," an vacuum feed system that keeps envelopes registered through the print zone regardless of flap position. The iJetColorQ pairs a rotary vacuum pick-up feeder with roller-based alignment, loading up to 1,000 envelopes at once.
Pigment Ink Matters as Much as the Printhead
Dye-based inks are soluble and can smear or fade depending on the media. Pigment-based inks sit on the surface and resist water and abrasion better. iJetColor's HP 990 pigment inks carry RISE certification under ISO 11798, the international standard for evaluating the permanence and durability of printed information, testing that covers light exposure, water resistance, and abrasion.
That certification matters for mail that spends days in transit or risks a rainy mailbox.
Durable ink is only part of what makes short-run envelope work practical. Offset presses need plates and cylinders before a single sheet runs, which only makes economic sense at high volume. Inkjet skips that step entirely. On a console-based iJetColor press, changing jobs takes one or two test envelopes, not a plate change.
The iJetColor Product Lineup: Choosing the Right Model
iJetColor's lineup spans three tiers: benchtop, console, and industrial packaging press, so a two-person print shop and a national mail house can both find a machine sized to their volume.
iJetColor 1175 (Benchtop)
The 1175 is the entry point: an affordable, compact system built on HP PageWide thermal inkjet and the HP FI-1000 printhead. It's designed for shops testing full-color, short-run envelope production before committing to a larger console model.
- Prints up to 7,810 #10 envelopes per hour
- Handles feed sizes up to 11.75" x 13"
- Built for roughly 20,000–50,000 envelopes per month
- Uses the same water-, fade-, and scratch-resistant pigment ink as the rest of the lineup
iJetColor 1175 Pro
The 1175 Pro is iJetColor's most widely installed model and winner of the 2020 Printed United Alliance Product of the Year award in the digital press category. It is built for shops producing 150,000 or more envelopes monthly.
- Scales from 4,285 to more than 10,000 envelopes per hour
- Heavy-duty vacuum feeder with optional high-capacity auto-loader for longer unattended runs
- Adjustable printhead height up to 2 inches
iJetColor 1175C
The 1175C takes the console architecture that made the Pro successful and prices it closer to the benchtop tier. Dealer partner SumnerOne has called it "the affordable version of the 1175 Pro."
Built on HP PageWide technology, it uses a single-operator feeding and alignment system—no separate alignment unit required.
- Rated 6,210 to 10,000+ envelopes per hour
- Envelope sizes up to 12" x 14"
- Recommended volume above 100,000 envelopes monthly
iJetColor Pro PXG and iJetColorQ
For packaging and ultra-high-volume work, iJetColor offers two specialized systems:
- Pro PXG: pairs the 1175 Pro engine with package automation for boxes, bags, and bubble mailers up to 14" x 20" and ½" thick
- iJetColorQ: HP TIJ4.0 printbar rated up to 20,000 #10 envelopes per hour—roughly double the 1175 Pro/C at top speed—with a rotary vacuum feeder holding up to 1,000 envelopes
Quick pick by monthly volume:
- 20,000–50,000: start with the 1175 benchtop
- 100,000+: 1175C for console capability at a lower entry price
- 150,000+: 1175 Pro for unattended, high-volume envelope runs
- Packaging or 20,000/hr envelope peaks: Pro PXG or iJetColorQ
Key Benefits & ROI of Switching to Inkjet Envelope Printing
The financial case for inkjet comes down to what you stop paying for: plates, extended makeready, and wasted stock on short runs.
Setup Time Measured in Envelopes, Not Hours
Offset requires new plates and blanket adjustments for every job change. Console-based iJetColor presses need one or two test envelopes to dial in registration and color.
Smithers research ties inkjet's short-run advantage directly to avoiding the cost and time of making plates or cylinders. That advantage shows up on the shop floor as faster job turns and less wasted stock.
Print-on-Demand and Variable Data
Because there's no plate holding a fixed image, every envelope in a run can differ. That opens the door to:
- Personalized names, addresses, and offers on direct mail
- Sequential numbering for security or tracking purposes
- Full-bleed, four-color graphics without a separate hit for variable text
Loris Printing, an iJetColor customer, found that a small increase in ink cost was outweighed by eliminating offset-related expenses entirely. Running setups of just one or two envelopes cut waste substantially.
Payback in as Little as 12 Months
A simple production model shows payback clearly: a shop running around 20 orders a month at 1,000 envelopes each, averaging $200 per order, can recover its equipment investment within a year. Real-world results vary with utilization and pricing. Every job that used to leave the building for offset printing now generates margin in-house instead.
Bringing Outsourced Work Back In-House
Capacity matters here. The 1175 Pro supports monthly output above 150,000 envelopes, enough for most shops to absorb jobs they previously farmed out. Spectrum Printing added an iJetColor Pro when its toner machine, capped around 5,000–6,000 envelopes per hour, couldn't keep up with short-run demand. Bringing that work in-house improved its bottom line directly.
How to Choose the Best Envelope Printer for Your Business
Picking the right press starts with honest numbers, not the fastest machine on the spec sheet.
Match the Model to Your Actual Volume
- Under 50,000 envelopes/month: A benchtop system like the 1175 covers short-run, full-color work without over-buying capacity you won't use.
- 100,000+ envelopes/month: Console models like the 1175C or 1175 Pro are built for sustained, single-operator production.
- 20,000+ envelopes/hour or packaging formats: The iJetColorQ or Pro PXG fit high-volume mail houses and packaging runs.
Buy more capacity than your volume justifies and you tie up capital. Buy less and you hit bottlenecks the moment demand grows.
Check Ink Durability, Not Just Color Quality
If envelopes travel through the mail stream, get handled repeatedly, or risk moisture exposure, ink certification matters. Look for RISE testing under ISO 11798 for light, water, and abrasion resistance—the same standard iJetColor's HP 990 pigment inks carry. Don't take a generic "water-resistant" claim on faith.
Prioritize Manufacturer-Direct Support
Downtime on a press running 150,000 envelopes a month gets expensive fast. Require manufacturer-direct support: dedicated service engineers, live response within the hour during business hours, and next-day parts under an active contract. iJetColor's MFG Direct Support model is built around those terms, without routing you through a third-party reseller.
Industries That Rely on Inkjet Envelope Printing
Inkjet envelope presses fit shops and in-plants where short-run flexibility and speed both matter.
Commercial Print Franchises and Mailing Providers
Franchise networks compete on turnaround and price, so inkjet's low setup cost is a natural fit. iJetColor customers in this segment include:
- AlphaGraphics, Minuteman Press, Sir Speedy, PIP Printing, and Allegra locations
- Online trade printers such as 4over that fulfill mixed jobs without offset makeready
Government, Education, and Election Printing
Institutional mail has to be accurate, secure, and often produced under a hard deadline. Michigan Election Resources uses an iJetColor Pro to produce millions of absentee ballot envelopes, switching sizes and quantities quickly under tight deadlines.
University mailrooms and other institutional in-plants run the same class of system for membership and enrollment mailings.
Corporate In-House Print and Fulfillment
Insurance companies, e-commerce fulfillment centers, and other high-volume mailers increasingly print envelopes in-house instead of sending every job out. Grange Insurance's team, for example, has produced 70,000 images on its iJetColor Press and gained the design flexibility customers notice on the finished piece.
Frequently Asked Questions
What is the best printer for printing envelopes?
The best printer depends on your monthly volume, budget, and quality requirements. For shops needing full-color, short-run flexibility, inkjet console presses like the iJetColor 1175 Pro or 1175C are a common recommendation.
What is an inkjet printer?
An inkjet printer is a digital device that fires microscopic ink droplets through nozzles to build an image directly on a substrate. There are no plates or dies involved, which is what makes on-demand, job-to-job printing possible.
How much does an inkjet envelope printer cost?
Pricing varies significantly by tier, from entry-level benchtop units to industrial packaging presses, and quotes are typically provided on request rather than published. Factor in the payback period, not just the sticker price.
What is the difference between inkjet and offset printing for envelopes?
Offset uses plates and cylinders, which makes it efficient at very high volumes but expensive to set up for short runs. Inkjet skips the plate entirely, printing directly and on-demand, which favors short runs and variable data.
How fast can inkjet envelope printers print?
Speeds vary by model. The entry-level iJetColor 1175 runs up to 7,810 envelopes per hour, the 1175 Pro and 1175C reach past 10,000, and the industrial iJetColor Q tops out at 20,000+ envelopes per hour.
Can inkjet envelope printers handle variable data and personalization?
Yes. Because there's no fixed plate image, inkjet presses can print a different name, address, or graphic on every envelope without slowing production or adding job cost.
