Solvent Printing:
Location tips and general maintenance of your solvent printers

Solvent printers in the All Print Supplies Media Test Centre - providing tips and guidance on hand,ing, printing and storage of our range of solvent printing media.Over the years we have been asked by many customers for support and detailed information on the best practice with solvent printers and also for maintenance tips on the machines.
Whilst we focus on consistent good quality media, we have a large amount of experience in printing all types of media in our print room. From this we have put together the following tips and hints to help maintain your machines.

Careful consideration needs to be given to these points:

  • Location of your solvent printer
  • Regular cleaning routines of the printer, inside and out
  • General upkeep and cleanliness of the printer and it's surrounding area
  • Maintaining consistent, correct room temperature
  • Ventilation / Air flow

LOCATION OF YOUR SOLVENT PRINTER:

Your printer must be kept clean and in a dust free environment. This is critical to ensure the print output is also clean and dust free. Our printers are regularly wiped down with a slightly damp cloth to keep dust levels to a minimum. This includes all flat surfaces of the machine, including the legs!
The floor area is kept clean, all packaging, media off cuts and old prints are kept away from the printer. This helps to avoid any accidents where rolls can fall over and contact the printer or prints! We recommend the use of roll holders to store media on. These have saved us a lot of problems.
The printer needs to be kept away from large extremes of temperature and humidity. Very high temperatures can have a negative impact on the drying of media, with the inks not having enough time to flow. Low temperatures can have a big impact on media drying times and lead to problems with printed media sticking to itself on either take up rolls or the floor. Keeping the printer at around 18 – 24°C has worked very well for us over the years.
Ventilation to allow an air change is also important to prevent a build-up of solvents or heat in the print room. This also provides a good environment for the print operator!

Solvent printers ventialltion is important so choose where you locate your solvent prointer carefully before installation!

MAINTENANCE OF YOUR SOLVENT PRINTER:

Careful care and cleaning of your solvent printer will result in better performance and quality - shown here is the print operator carefully cleaning the capping station with a cotton swab.All new printers are sold with a manual detailing clearly the steps you need to take to keep the machine in good condition. These daily, weekly and monthly routines are absolutely critical to ensure the printer and print head are kept in optimum condition.
Because solvent ink will naturally dry quicker than a water based ink, the cleaning of the printer, the heads and the media carriage is important to keep your machine in tip top condition and ensure output is perfect day after day.
Each machine is slightly different, so it's almost impossible to spell out here the individual steps for each solvent printer currently on the market. However your printer manufacturer should be able to assist you in finding the correct schedule for your particular machine. The web is also a great place to pick up the appropriate tips and hints on maintenance.
We always carry out a nozzle test before carrying out any work. It's a rapid and very easy method of checking your printer is in good condition. It should be printed as a series of sharp well defined lines in each of the print colours. Any deviation, in terms of wavy lines or missing lines is an indication your machine may need maintenance action.
