Quick Answer
Ultrasound thermal paper is sized by width × length. Sony's 110mm printers (UP-895 / 897 / 898 Series) take 110mm rolls: UPP-110HG is 110mm × 18m, while UPP-110S and UPP-110HD are 110mm × 20m. Durico's compatible 1100HG (18m), 1100S and 1100HD (20m) match those dimensions exactly — so they drop straight in with no adapters and no guesswork.
If you've ever stood in front of an ultrasound printer holding a roll of paper and wondered why one box says 110mm × 18m and another says 110mm × 20m — this guide is for you. Roll geometry is the least glamorous line on a thermal paper spec sheet, but it's the one that decides whether a roll physically works in your printer at all. Here's what each number means, why the lengths differ between grades, and how to read a spec label with confidence.
The Two Numbers That Matter: Width and Length
Every ultrasound thermal paper spec follows the same format: width × length. A "110mm × 20m" roll is 110 millimeters wide and unrolls to 20 meters of printable media.
Width: determined by your printer, non-negotiable
Width is the number you have zero flexibility on. Sony's medical thermal printers are built around fixed media widths, and the paper compartment, feed path, and thermal head are all engineered for one width class:
- 110mm class — Sony UP-895 / 897 / 898 Series printers (the A6-format workhorses found beside most ultrasound carts). These take UPP-110 series paper — and the Durico 1100 series equivalents.
- 210mm class — Sony UP-970 / 971 / 990 / 991AD large-format printers. These take UPP-210HD — and the Durico 2100HD equivalent at 210mm × 25m.
A 110mm roll will not work in a 210mm printer, and vice versa. There is no adapter, no workaround, and no reason to try. When in doubt, check the printer model number first — the width follows automatically.
Length: determined by the paper grade
Length is where the spec sheets get interesting. Within the same 110mm width, roll lengths differ by grade:
- High-gloss (Sony UPP-110HG / Durico 1100HG): 110mm × 18m
- High-density (Sony UPP-110HD / Durico 1100HD): 110mm × 20m
- Standard (Sony UPP-110S / Durico 1100S): 110mm × 20m
That 18m vs 20m difference is not a shortcut or a cost-saving trim — it mirrors the OEM (original equipment manufacturer — Sony-branded) paper exactly. Sony's own high-gloss UPP-110HG is an 18m roll, while its standard and high-density papers are 20m rolls, and Durico builds its compatible grades to the same geometry.
Why does the glossy roll carry less length? The practical constraint is roll diameter. Your printer's paper compartment accepts a fixed maximum roll diameter, and a media stack with more coating build — Durico's high-gloss grade uses a five-layer construction including a UV-cured gloss layer over the thermal coat — reaches that diameter in fewer meters. Standard and high-density media wind slightly more length into the same footprint. Either way, the roll that matches your grade fits the compartment as designed.
Compatibility Table: Sony Spec → Durico Equivalent
| Sony paper | Durico equivalent | Roll geometry | Sony printers | Where to buy |
|---|---|---|---|---|
| UPP-110S (Type I, standard/matte) | Durico 1100S | 110mm × 20m | UP-895 / 897 / 898 Series | Durico 1100S (5-roll box) |
| UPP-110HG (Type V, high-gloss) | Durico 1100HG | 110mm × 18m | UP-895 / 897 / 898 Series | Durico 1100HG (5-roll box) |
| UPP-110HD (Type II, high-density) | Durico 1100HD | 110mm × 20m | UP-895 / 897 / 898 Series | Durico 1100HD (5-roll box) |
| UPP-210HD (Type II, large format) | Durico 2100HD | 210mm × 25m | UP-970 / 971 / 990 / 991AD | Durico 2100HD (5-roll box) |
Note: the Durico 1100HG is also compatible with Mitsubishi P93 / P95 printers (Mitsubishi paper codes K95H / K91HG / KP91HG). The 1100HD, 1100S, and 2100HD grades are Sony-only.
Why Matching OEM Geometry Matters
A compatible roll only deserves the name if it matches the OEM roll's physical dimensions. Here's what exact-geometry matching buys you in practice:
Drop-in fit. A 110mm × 20m Durico 1100S loads into a UP-X898MD exactly the way a Sony UPP-110S does — same compartment, same feed path, no trimming, no adjustment. If a roll needs persuading to fit, it isn't compatible; it's a liability.
Predictable supply planning. Because lengths match OEM spec, your usage math doesn't change when you switch. A department that went through a case of 20m OEM rolls per month will go through Durico 20m rolls at the same rate. You're changing the price per roll, not the workflow.
No thermal-head surprises. Geometry is only part of the fit story — media thickness and surface also have to behave correctly under the thermal head. Durico's 1100 series pairs its OEM-matched dimensions with a built-in anti-static layer designed to protect the thermal head, and a five-layer construction engineered for smooth head matching. For a deeper look at what's inside the media stack, see the guide to thermal paper specifications for medical imaging.
Reading a Spec Label in Five Seconds
Every roll decision comes down to three checks, in order:
- Printer model → sets the width. UP-895/897/898 Series = 110mm. UP-970/971/990/991AD = 210mm.
- Paper type your workflow needs → sets the grade. Standard (matte, most economical) for everyday clinical prints; high-gloss for keepsake-quality images; high-density (semi-glossy) for high-contrast grayscale work. Not sure which? The comparison of UPP-110HG vs UPP-110HD vs UPP-110S walks through the decision.
- Grade → sets the length automatically. High-gloss = 18m; standard and high-density = 20m; large-format high-density = 25m.
That's the whole system. Width from the printer, grade from the workflow, length from the grade.
A Few Geometry Details Spec Sheets Don't Explain
Roll weight tracks the media, not just the length. Durico's published packing specs show a 20m roll of 1100HD at 0.178 kg and a 20m roll of 1100S at 0.16 kg — same length, different weight, because the high-density media stack carries more coating. The 18m high-gloss roll comes in at 0.157 kg. None of this changes how you load or use the paper; it's simply a reminder that grades are physically different products, not the same base paper with different labels.
Each roll ships sealed in its own foil pouch. Thermal media is heat- and humidity-sensitive by design, so Durico individually seals every roll in a foil pouch inside the 5-roll box. Leave rolls sealed until you load them. For how storage affects media over time, see how long an ultrasound thermal paper roll lasts.
Packaging math differs by width. The 110mm grades pack 5 rolls per box and 50 rolls per carton; the 210mm 2100HD packs 5 rolls per box and 25 rolls per carton. If you're ordering at carton scale for a multi-room department, that difference matters for storage planning.
What Matching Geometry Costs (Hint: Less Than OEM)
Dimension-for-dimension, Durico's grades match the Sony spec while running roughly 25–30% less than OEM media. At current Precision Imaging Supply pricing, that works out to:
- Durico 1100S (110mm × 20m, matte) — $43.95 per 5-roll box, about $8.79 per roll — view current price
- Durico 1100HG (110mm × 18m, high-gloss) — $64.95 per 5-roll box, about $12.99 per roll — view current price
- Durico 1100HD (110mm × 20m, high-density) — $64.95 per 5-roll box, about $12.99 per roll — view current price
- Durico 2100HD (210mm × 25m, large format) — $199.95 per 5-roll box, about $39.99 per roll — view current price
Sony OEM list pricing varies by reseller, but the compatible route consistently lands in that 25–30% savings range per roll. Higher-volume practices can step up to the 1100S 10-roll box, 1100HG 10-roll box, or 1100HD 10-roll box for better per-roll economics.
Frequently Asked Questions
Why is high-gloss paper 18m when standard paper is 20m?
The high-gloss media stack carries additional coating — including a UV-cured gloss layer — so it reaches the printer compartment's maximum roll diameter in fewer meters. Sony's own UPP-110HG is an 18m roll for the same reason, and Durico's 1100HG matches that OEM geometry exactly.
Are Durico rolls the same physical size as Sony rolls?
Yes. Each Durico grade matches its Sony equivalent's published roll geometry: 1100HG at 110mm × 18m (UPP-110HG), 1100S and 1100HD at 110mm × 20m (UPP-110S / UPP-110HD), and 2100HD at 210mm × 25m (UPP-210HD). They load and feed as drop-in replacements.
Can I use 110mm paper in a Sony UP-970 or UP-991AD?
No. The UP-970 / 971 / 990 / 991AD are 210mm large-format printers and require 210mm media such as the Durico 2100HD. Width is fixed by the printer's compartment and thermal head — always match it first.
Does a longer roll mean lower cost per print?
All else equal, more meters per roll means fewer roll changes and more prints between swaps. But grade matters more than length for cost: the 20m standard (matte) grade is the most economical choice for everyday clinical printing, while the 18m high-gloss grade is priced for presentation-quality output.
Which Durico paper works with Mitsubishi printers?
Only the 1100HG. It's compatible with Mitsubishi P93 / P95 printers (replacing Mitsubishi K95H / K91HG / KP91HG media) in addition to the Sony UP-895 / 897 / 898 Series. The 1100S, 1100HD, and 2100HD are Sony-only grades.
Do the rolls come individually sealed?
Yes. Every Durico roll is individually sealed in a foil pouch inside the box, which protects the thermal coating from heat, humidity, and light until you're ready to load it.
Is Durico paper made to medical-market quality standards?
Durico media is FDA registered and manufactured in South Korea by Durico Coating & Technology, a self-manufacturer certified to ISO 9001, ISO 14001, and ISO 13485.
