Humidity Control in Printing and Graphic Arts<\/h2>[vc_column_text]Paper has hygroscopic properties, that is, its moisture content varies in accordance with the humidity of the surrounding environment.<\/p>\n

Moisture control is very important in the printing process as excessive moisture can cause jams in the press and heating on the rollers during production.<\/p>\n

Adversely, if an environment becomes too dry, it can change the physical properties of the paper; contraction of dimensions or ripples on the surface, since these are determined by moisture content.<\/p>\n

With a humidification system in place it is possible to maintain a constant RH suitable for the product, therefore protecting quality and contributing to increased productivity.[\/vc_column_text][\/vc_column][vc_column width=”2\/5″][vc_empty_space][vc_single_image image=”18275″ img_size=”large”][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space][vc_separator][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column width=”2\/3″][vc_column_text]Static electricity can often develop on dry paper that passes through a printing machine with low relative humidity.<\/p>\n

When the RH drops to 40%, the static electricity will increase. This causes the paper to stick and break, interferes with smooth running and makes stacking a problem.<\/p>\n

Static load is the most common cause of disruption in continuity of work in the printing process.<\/h4>\n

Screen printing is a technique used to reproduce documents and images onto any material. It involves transferring an ink, through a mesh, which is tensioned in a frame.<\/p>\n

The drying phase of the process is of vital importance, as it determines the level of adhesion and therefore, the durability of the finished, printed product.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”17903″ img_size=”large”][vc_message]For more information contact our experts.<\/a>[\/vc_message][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space][vc_separator][vc_empty_space][vc_column_text]Fisair has created specific humidification equipment which can maintain the correct RH levels required for your space.

Isothermal Humidification:<\/h3>\n

This process involves the introduction of water vapour, generated by boiling water, into the environment.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_column_text]<\/p>\n

Adiabatic Humidification:<\/h3>\n

This involves the direct evaporation of water into the air, without the input of external energy.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space][vc_separator][vc_empty_space]

Application References<\/h3>[\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_column_text]Fisair works closely with multinational Tetra Pak<\/strong> to maintain the moisture levels in its production and storage areas.<\/p>\n

The systems used are diverse, and depend on the suitability of each internal application: Adiabatics by pneumatic atomization<\/a> and Isothermal by submerged electrodes<\/a>.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image image=”15194″ img_size=”medium”][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space][vc_separator][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column]
