Heidelberg XL 106 vs. Komori G40P — Comparing Offset Printing Technologies
Heidelberg XL 106 vs. Komori G40P — Comparing Offset Printing Technologies
On high-volume packaging, catalog and corporate print projects, the question "which press should this run on?" is decisive for turnaround time, unit cost and final quality. In Turkey, the two reference presses in this segment are the Heidelberg Speedmaster XL 106-8P+L and the Komori Lithrone G40P. Both are industry leaders, and each has its own distinct strengths. Both presses are active at Printer Ofset's Organize Matbaacılık facility — in this guide, we explain which jobs we run on which press, and why.

A quick look at both presses
Both the Heidelberg Speedmaster XL 106 and the Komori Lithrone G40P are B1-format (70×100 cm) offset presses. Each is a "perfector" configuration (a setup that prints both sides of the sheet in a single pass), built on 8-colour-plus-coating (8 process colours + coating) technology. Both can reach speeds of up to 18,000 sheets per hour.
That said, they are not "the same press." Their engineering philosophies differ:
- Heidelberg (German heritage) — mechanical precision + software automation integration
- Komori (Japanese heritage) — paper transfer flow + stability optimization
In practice, this difference means each press is better suited to a different type of job.
Heidelberg Speedmaster XL 106-8P+L
The Heidelberg Speedmaster XL 106 series is the B1-format flagship of Germany's Heidelberg Druckmaschinen AG. The "P" stands for Perfecting (two-sided printing), and "L" stands for the coating (lacquer) unit. In other words, in a single pass:
- The front of the sheet is printed in 8 colours
- In the same pass, the sheet is turned and the reverse side is printed
- A coating (gloss/matte or UV lacquer) is then applied
This configuration reduces the number of machines in the chain on high-volume catalog and corporate brochure production — losses that occur as paper moves from one press to another (dust, heat, mixing) are minimized.
Prinect workflow integration is one of Heidelberg's defining features. From the CIP3/CIP4 file through to prepress, press time and finishing, every stage is fed from the digital file. Color control, ink consumption and paper usage are reported in real time. Printer Ofset's operations team pre-tests every job in a Prinect simulation before it starts.
Strengths:
- High automation → short makeready (~20 minutes to start an 8-colour job)
- Pantone color repeatability at the highest level (ΔE <1.5)
- Seamless integration of coating + foil stamping + lamination
Practical limitations:
- Complex paper transfer may not be optimal on certain special substrates (very thin board, aluminum foil)
- Spare parts and service fall in the high-cost segment
Komori Lithrone G40P
The Komori Lithrone G40P is the top model in the B1-format series from Japan's Komori Corporation. "G40" refers to the format (frame size), and "P" is the perfecting version. The 5-colour-plus-coating Lithrone G40P in Printer Ofset's inventory stands out in particular for its stable paper transfer and minimal waste.
Komori's engineering philosophy diverges from Heidelberg's through a paper transfer system called "Komorimatic." The airflow between each transfer cylinder, the vacuum pressure and the mechanical tolerances are all very tightly calibrated — the result: minimal paper deformation even at high speed, and low sheet loss (creasing, tearing).
KP-Connect software is Komori's own workflow solution. While it doesn't offer an ecosystem as comprehensive as Heidelberg's Prinect, the Japanese design principle of "not tying the operator's hands" makes Komori flexible.
Strengths:
- Stability on light/slippery papers (thin kraft, foil laminate)
- Parallel workflow compatibility — different customer jobs can be queued back to back
- Lower long-term operational cost (spare parts, service intervals)
Practical limitations:
- Pantone color repeatability requires slightly more manual intervention than Heidelberg
- Smaller software ecosystem — limited third-party integrations

Which job do we choose which press for?
The practical decision made by Printer Ofset's operations team depends on three critical variables of the project: color precision, paper type and delivery time.
Heidelberg XL 106-8P+L is preferred for:
- High-volume (50,000+ units) corporate catalogs, annual reports and brochure projects
- Packaging requiring 6+ Pantone spot colors (premium cosmetics, food)
- Reprint projects — cases where the same Pantone value must be matched to a previous run
- Combined finishing chains of UV coating + spot UV + foil stamping + lamination
Komori Lithrone G40P is preferred for:
- High-volume wholesale brochure and newspaper-style jobs on light paper (60–80 g)
- Printing on kraft paper (kraft bags, brown paper packaging)
- Fast-rotation agency work — corporate production where different customer projects are queued throughout the day
- Cost-optimized, standard CMYK projects (where 5 colours + coating is sufficient)
Hybrid approach: different pages of the same project can run on different presses. For example, the 4-color inside pages of a 100-page annual report run on the Komori, while the 7-color + coated cover and photo pages run on the Heidelberg. This hybrid architecture is one of Printer Ofset's B2B advantages.
Frequently asked questions
Is there a difference a designer needs to know about between the two presses?
From a design standpoint, both presses accept the same file format (PDF/X-4, ICC color profile). However, on projects where Pantone color fidelity is critical, sharing which press the job will run on with the operations team allows a more precise color proof to be prepared.
Which press has the newer technology?
Both brands issue active model updates every year. Heidelberg's Prinect Workflow software provides broader automation across the production chain. Over the past 3 years, Komori has made major advances in its paper transfer sensors. The technology is on an equal footing — what matters is which one fits your job.
How is color consistency guaranteed across multiple print runs?
On both presses, color is measured with an X-Rite spectrophotometer. For Pantone spot color orders, a standard reference print is prepared before each batch; subsequent batches are calibrated against that print. A tolerance of ΔE <2.0 is the standard commitment.
Are these presses economical for very small runs?
No — for both B1 offset presses, plate preparation, ink washup and operator time are fixed costs. For projects under 1,000 units, the HP Indigo 12000 at Printer Ofset's Digital Offset facility is the more economical choice.
Which ICC profile is the color standard on export projects?
ISO Coated v2 (ECI) is the standard output profile. This profile is a widely used reference in EU, US and Far East markets. On special request, a GRACoL or JapanColor profile can be applied.
