An Overview of Automatic Garment Presses

Use this guide to automatic garment presses to find out about important features and functions and learn about some of the models on the market.

Automatic garment presses are designed to deliver print-production speed and accuracy, access to more colors and effects, and higher levels of consistency and output quality. Many models are available to accommodate new shops or facilities without much floor space to spare, growing businesses that need greater capacity than manual presses can offer, and large-scale operations that print garments in the millions. Before we look at a cross-section of what’s on the market, let’s review some of the basics you’ll need to consider when shopping for an automatic garment press.

Configurations
The carousel configuration is the most common type of automatic garment press and is the focus of this article. Its operation is similar to that of the manual press—that is, it indexes in a circular pattern. Oval presses are still available, though the number of domestic manufacturers that offer this type of machine has decreased significantly over the years. As its name implies, the oval press is longer than it is wide. It typically is modular in design and indexes shirts along a track on the perimeter of the press.

Carousel presses require unobstructed areas that are larger than their total circumference, otherwise known as footprint, to give operators access to all print stations and press controls. Shop floors that are peppered with ceiling-support pillars or other structural components can limit the maximum allowable press size. An oval press may be a good solution in places where broad, open areas are unavailable.

Colors and stations
Automatic garment presses are available with as few as four colors/six stations to more than 18 colors/20 stations. Auto-matics typically feature two more stations than colors to provide for garment loading and unloading. Some configurations are designed specially for single-operator use and are equipped with only one extra station dedicated to loading and unloading. Be sure to take into account the flash-curing positions you’ll need—as well as positions dedicated to underbases, specialty inks, and more—when deciding how many stations you want.

Drive systems and press movement
Pneumatic, electromechanical, and servomechanical drives are the most common types used in the operation of automatic garment presses. Some machines use one type of drive; others combine them. Pneumatic systems use pressurized air to index printing platens and/or to power squeegee/floodbar assemblies. Electronic valves control speed and distance of motion. Presses with strictly pneumatic drive systems are often less expensive than models that use electromechanical or servomechanical drives.

Electromechanical drives typically have electric motors and analog controls that are used to index the press and/or power the printheads. AC and DC drive motors may be incorporated into the printheads for greater movement control.

Servomechanical drives are often regarded as the most precise in terms of accurate press movement. Digitally controlled servomotors provide continuous feedback to the press’s control system to ensure exact position. Automatic garment presses may be completely servo driven or equipped with a servo indexer and pneumatic or electromechanical printheads.

Press movement refers to the press’s actions after indexing. Some automatics raise the platen to the screen for the print stroke. These are referred to as platen-lift presses. Others lower the screen from a raised position before the print stroke. These are called screen-lift presses. Each has its supporters, so it’s best to see a variety of presses at work before making a selection.

Clamping, frame size, and image area
Most automatic presses are equipped with pneumatic frame clamps. They may grip the frames along one edge or multiple edges. Generally speaking, the more sides of a frame that are clamped, the greater the stability and registration accuracy of that frame during printing. Note that several manufacturers offer pin-registration systems designed to speed up screen alignment on press.

Frame size determines the frame format the press will accept. If the automatic press you like won’t support the frames you currently use, you’ll have to switch to new frames. Image area refers to the largest image size you’ll be able to print. Make sure the press you’re checking out will permit you to print garment graphics at acceptable sizes. Note that some press models feature optional attachments that allow you to switch between standard-sized prints and large-format or all-over prints.

Cycle speed
Cycle speed is, perhaps, the greatest draw for automatic presses. The maximum cycle speed refers to the number of prints a press can produce with one or two operators in an hour. Some presses support the decoration of several hundred garments per hour; others can produce more than a thousand in that time. Realistically, actual cycle speed depends on how many colors you print, how many flash sequences are in the workflow, the types of inks you print, and other job-specific factors.

Controls
Control systems range from analog dials and switches to microprocessor-based systems with touchscreens. Digitally controlled presses typically feature a master control system and independent controls on each printhead for fine tuning. Some models allow operators to store and recall job settings, which can reduce setup time significantly on repeat orders. Some presses also feature connectivity solutions that permit manufacturers to access control systems and troubleshoot problems remotely.
