The Lawson Seneca is a simple, easy-to-use graphic flat-bed press. The Seneca is fast to set-up and includes many of the features found on much more expensive presses. In addition, Lawson's reputation for dependability and easy service is always standard. The Seneca provides maximum control of the printing process. Lawson's exclusive Load-Leveller, Single-Point Peel System and Dial Indicator Controls are standard. It has been engineered to print fine line half-tones, ultraviolet inks, printed circuits, plastics, glass, transfers, water-based inks and much more.


The Seneca is a heavy-duty press offering the ultimate in user-friendly versatility, adjustment and control. Operator controls are all up front, easy to use and clearly marked. The computer-driven, state-of-the-art electrical control system provides maximum power, reliability, consistency and simplicity.



Reasons To Buy A Lawson Seneca

  • Auto-Flood Capability: Keeps the screen flooded (European style) while the screen is in the open position, or unflooded (standard U.S. style), with a simple flip of a switch.
  • Load-Leveller: Lawson's exclusive Load-Leveller solves the problem of "unbalanced" squeegee pressure and/or loss of squeegeelizer control. Now you can precisely control the placement of squeegee force and pressure location. Simply slide the squeegee posts where you desire. As a result, center and side deflection are eliminated by placing the "chopper/squeegee system" where the force is balanced (not overhung on the outside of the print area)! Better resolution and registration is achieved because less squeegee pressure is required and the squeegee is placed exactly where needed.
  • Unique Peel System: Direct-Action Peel allows adjustment of peel/off-contact at one point and at the front of the screen carriage, without tools. Peel settings are stepless, direct-acting and air-assisted (for heavy weight frames) and allow for more accurate and visible control at the squeegee/print contact point. Dial-Indicator Controlled.
  • Dial Indicators: Allow registration with fast, precise movements of the registering table. Micro-adjustability is easily achieved with the Seneca's "floating table" that moves without friction on roller bearings and is monitored in .001-inch increments via three dial indicators.
  • Solid Aluminum Vacuum Table: An all aluminum honeycomb core ensures flatness and resistance to all solvents, for the life of the press! Other systems, although they may have aluminum tops, the actual support core is not aluminum. As a result, warpage and deterioration can occur. In addition, the Seneca's registering vacuum table glides on roller bearings for a "smooth as glass" feel during micro-registration.
  • Air-Balanced Squeegee (Squeegelizer): Provides accurate, uniform, easy control of squeegee pressure. Automatically balances squeegee pressure from side to side to assure uniform control of ink deposit. Control is up front, and no tools are necessary. Pressure can be adjusted while press is in operation and documented with the dial pressure gauge on the face of the control panel.
  • Masterframe: Accommodates all frame profiles up to three inches high. Easy to adjust and lock. Does not rest on print table, allowing exact control of off-contact and peel position with true"on contact" setting ability. Side screen loading is standard.
  • Timing Belt Carriage Drive: Smooth, quiet, vibration and chatter-free. Never needs adjusting or grease like chain-driven machines.
  • Adjustable Stroke Length Sensors: Adjust the length of the print stroke in seconds, front and rear, with no tools. Lawson's unique sensor design is safer, easier and more reliable than any other on the market.
