I want a B2 size 4-5 colour offset press

I am currently operating two B2-size Heidelberg SORMZ presses, each with a 2x2 color configuration. Due to frequent downtimes, I am considering upgrading to a four-color press to expedite CMYK jobs. The majority of my work involves spot colors, typically ranging from one to three. I am evaluating the Komori Enthrone series and Heidelberg models produced after 2005. My objectives include completing ten make-readies per day and enhancing efficiency. Additionally, I primarily print on paperboard with a thickness of up to 350 GSM. I seek insights into the following:

1. Compatibility with 350 GSM Paperboard: Can the Komori Enthrone series handle substrates up to 350 GSM?
   
   
2. Spot Color Vibrancy: Does the Enthrone series produce vibrant spot colors?
   
   
3. Comparison with Newer Heidelberg Models: How do newer Heidelberg presses compare in terms of performance and reliability? Is Komori press reliable and take some abuse?

I would appreciate expert guidance on these considerations, as I am cautious about relying solely on sales representatives, and most of my industry peers operate used machinery.

 

Hi sir
If you prioritize thick substrates, frequent job changes, and long-term reliability, a post-2005 Heidelberg press (like SM or XL models) would be the better investment. However, if budget constraints are a concern and you're willing to trade a bit of automation for a lower upfront cost, Komori Enthrone remains a solid and reliable option.
I will tell you why :
- Both perform well, but Heidelberg often offers better consistency over longer runs due to its sophisticated color management technology
- Heidelberg has a slight edge for thicker stocks due to its reputation for precision and substrate versatility.
- If your objective is ten make-readies per day, Heidelberg models are better suited for this demand. Komori can handle it but may require more manual intervention.
If you need more detail let me know
Good luck

 

1) What are the most significant differences between an Enthrone and a Lithrone? An investment in a printing press is no small thing, don't cut necessary corners based solely on price - newer presses mean newer technology… Lithrones are the way to go.

2) I can tell you that Lithrone (L, LS, and LSX series) presses will all pretty much print on up to 20pt. board, without having to open any gripper settings. And on a press that’s been maintained (taken care of) correctly, Komori print quality is just about as good as it gets.

 

I recently had the opportunity to visit several printing facilities featuring both Heidelberg and Komori press models. During these visits, I received valuable feedback regarding substrate compatibility, particularly concerning 350 GSM board for the Komori Enthrone.

According to the printer's recommendations:

• Double-side coated board is suitable for use
• Single-side coated or uncoated board is not recommended
• The maximum substrate thickness for their Komori press is kept below 0.55 mm

I noted that both the Heidelberg SM and Komori Enthrone have maximum board thickness specifications of 0.6 mm, which is less than my current Heidelberg SORMZ (capable of handling up to 0.8 mm).

Given these considerations, I am evaluating the Heidelberg CD press as an alternative option, though I understand these models are approximately 1.5 to 2 times the price of the SM series. My primary concern is determining whether the additional investment in the CD model is justified for long-term, hassle-free printing with 350 GSM board.

Key priorities for my operation include:

1. Preventing scratches on the reverse side of the board
2. Minimizing unnecessary downtime

I would greatly appreciate your professional assessment regarding whether the Heidelberg SM would be sufficient for my requirements, or if the CD model would be a more appropriate long-term investment.

Thank you for your expertise and guidance on this matter.

 

I have also evaluated the Komori Lithrone as a potential option. However, I have identified several financial and operational concerns:

The new Komori Lithrone press represents a significant capital investment:

• 3-4 times the cost of a pre-owned Heidelberg CD
• 4-5 times the price of a pre-owned Heidelberg SM
• Comparable in cost to a new Heidelberg CX75

An important operational consideration is that our staff is already proficient with our existing Heidelberg SORMZ two-color press. This established familiarity creates a compelling case for remaining within the Heidelberg ecosystem unless the Komori alternative offers either:

• Substantial performance advantages
• Significant cost benefits

Given these factors, I am inclined to continue with Heidelberg equipment unless there is a compelling reason to transition to Komori that would justify both the additional investment and the operational adjustment period.

I welcome your professional perspective on this matter.
