OHIO builds engrave heads with the most advanced technology for flexibility, capability and productivity. The Vision 3 head includes Electronic Feedback Control for improved reliability and performance; spherical shoe diamond and cartridge stylus, shoe, and burr cutter for easy replacement; motorized shoe and burr cutter; and hysteresis correction to ensure optimum engraving results.
The Vision 3 high-speed, multi-frequency engrave head handles any screen size. It is standard equipment on the Spectrum and the Prism engravers, and was used on earlier engravers such as the HS engraver.
Changing and measuring the stylus is simple on OHIO engravers. No need to remove the engrave head, or have extra equipment. All diamonds are cartridge style for fast changes. With Spectrum and Prism Prime, electronic profiling stylus angle and condition is integrated with the engraver at no added cost.
Cells engraved by Vision 3 standard tunes are well formed in all screens and angles.
The Vision 3 engrave head comes with three standard tunes but may be upgraded with premium tunes. A premium tune replaces a standard tune. For example, a popular tune set is 8.1/1.7/Hybrid.
|Standard Tunes||Premium tunes|
|8,600 Hz for cell depths up to 35 µm||Hybrid Engraving System|
|8,100 Hz for cell depths up to 60 µm||Impact Engraving – 1,700 Hz for cell depths up to 90 µm|
|3,200 Hz for cell depths up to 70 µm||tranScribe — 4,500 Hz for cell depths up to 60 µm|
With the Hell Match or DTG Match option, the Vision 3 engrave head can engrave cylinders to match Hell-engraved cylinders without moiré.
OHIO offers two cell setup options on our engravers:
A benefit of gravure printing is increased ink volume. In applications where paper board, corrugated, or other absorbent substrates are used, the available Impact Engraving tune provides the volume for excellent ink coverage and color, and is perfect for coating applications and adhesives printing. This tune replaces one of the standard three tune on the Vision 3 engrave head.
OHIO offers the High Output head for deep cell volumes. This head is used when increase cell volume is required. It can engrave depths up to 130 µm, allowing screens up to 24 l/cm (with 120° stylus).
The unique High Output head is a mutli-frequency head for increased productivity:
Separate optics may be required.
The High Output head can be exchanged with the Vision 3 head, providing more versatility. The Rapid Change System to switch from the Vision 3 to the HO head only requires the Head and the Kaman components to be swapped during the exchange.
We offer the 300 Micron engrave head. This unique head was developed for very specialized gravure applications, providing extreme cell depths for very large ink volume. This head requires a special diamond tool to cut cells 300 µm deep at a speed of 800 cells per second (0.72 m2/hr at 20 l/cm). The stylus includes reinforcement of the stylus and a greater tip-to-shank distance (more diamond). These improvements protect the stylus and allow the extreme depths this head can achieve.
The 300 Micron head includes the following:
Higher force styli and a higher force vacuum system are used. Separate optics are required.

OHIO's engrave heads provide many years of trouble-free work, but over the course of time and use the performance of this hard-working head can degrade. If the working environment contains dirty air, this can significantly impact the head's performance.
The OHIO engrave head can give long years of service before needing any work done. Recently, a head that had been in production for 19 years was sent to OHIO for its first refurbishment.
Our years of experience in building and repairing engrave heads allow us to provide standard price quotes, based on the type and age of the head. The head is rebuilt with new parts as needed, then is tested, tuned and painted. Our experts in the Head Department can refurbish or repair an engrave to a "like-new" condition, with a warranty identical to that of a brand-new engrave head.
Please contact your local sales/service agent to request an RMA (Return Material Authorization) and shipping instructions. If you do not have a spare engrave head, please ask your local agent about the possibility of a loaner engrave head.
If you would like to manufacture diamonds for use with OHIO engrave heads, please contact us directly so we can provide you with accurate drawings.
