Abstract

An image forming system includes an image forming apparatus, a pressure sealing processing apparatus, and a control unit. The control unit is configured to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a grammage is smaller than a predetermined grammage, and is configured not to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a grammage is equal to or more than the predetermined grammage.

First claim

What is claimed is:

1. An image forming system comprising:
an image forming apparatus configured to form an image on a recording material;
a pressure sealing processing apparatus configured to execute a pressure sealing processing process of pressure-sealing the recording material by folding the recording material on which the image is formed by the image forming apparatus and applying pressure to the folded recording material; and
a control unit configured to control the image forming apparatus and the pressure sealing processing apparatus,
wherein the control unit is configured to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a grammage is smaller than a predetermined grammage, and is configured not to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a grammage is equal to or more than the predetermined grammage.

2. The image forming system according to claim 1 , further comprising an input unit configured to accept an instruction from a user based on an input operation by the user,
wherein the control unit is configured to control the input unit such that a selection input of the recording material of which the grammage is equal to or more than the predetermined grammage from the input unit is not permitted in a case where the pressure sealing processing process is included in the instruction from the user that is accepted via the input unit.

3. The image forming system according to claim 1 , further comprising an input unit configured to accept an instruction from a user based on an input operation by the user,
wherein the control unit is configured not to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus in a case where an instruction to perform the pressure sealing processing process on the recording material of which the grammage is equal to or more than the predetermined grammage is included in the instruction from the user that is accepted via the input unit.

4. The image forming system according to claim 3 , wherein
the input unit includes a display unit that displays information, and
the control unit is configured to perform warning display on the display unit in a case where the instruction to perform the pressure sealing processing process on the recording material of which the grammage is equal to or more than the predetermined grammage is included in the instruction from the user that is accepted via the input unit.

5. The image forming system according to claim 4 , wherein the control unit is configured to control the display unit so as to display, as the warning display, information for accepting cancelation of the instruction from the user which is accepted via the input unit.

6. The image forming system according to claim 4 , wherein the control unit is configured to control the display unit to display, as the warning display, information for accepting only image formation by the image forming apparatus based on the instruction from the user that is accepted via the input unit.

7. The image forming system according to claim 1 , wherein the pressure sealing processing apparatus includes:
an application unit configured to apply varnish on a surface of the recording material on which the image is formed by the image forming apparatus,
a folding unit configured to fold the recording material in a state in which the surface on which the varnish is applied by the application unit faces inward, and
a pressure sealing unit configured to apply pressure to the recording material folded by the folding unit.

8. The image forming system according to claim 1 , wherein the pressure sealing processing apparatus includes:
a folding unit configured to fold the recording material on which the image is formed by the image forming apparatus,
a supply unit configured to supply a heat-sensitive bonding film on an inside of the folded recording material, and
a pressure sealing unit configured to apply heat and pressure on the recording material in a state of being folded by the folding unit to sandwich the bonding film supplied by the supply unit.

9. An image forming system comprising:
an image forming apparatus configured to form an image on a recording material;
a pressure sealing processing apparatus that includes an application unit which applies varnish on the recording material on which the image is formed by the image forming apparatus, a folding unit that folds the recording material in a state in which a surface on which the varnish is applied by the application unit faces inward, and a pressure sealing unit that applies pressure to the folded recording material, and is configured to execute a pressure sealing processing process on the recording material on which the image is formed by the image forming apparatus; and
a control unit configured to control the image forming apparatus and the pressure sealing processing apparatus,
wherein the control unit is configured to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a surface is coated, and is configured not to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a surface is not coated.

10. The image forming system according to claim 9 , wherein the control unit is configured to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a surface is coated and a grammage is smaller than a predetermined grammage, and is configured not to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus on a recording material of which a surface is coated and a grammage is equal to or more than the predetermined grammage.

11. The image forming system according to claim 9 , further comprising an input unit configured to accept an instruction from a user based on an input operation by the user,
wherein the control unit is configured to control the input unit such that a selection input of the recording material of which the surface is not coated from the input unit is not permitted in a case where the pressure sealing processing process is included in the instruction from the user which is accepted via the input unit.

12. The image forming system according to claim 9 , further comprising an input unit configured to accept an instruction from a user based on an input operation by the user,
wherein the control unit is configured not to permit execution of the pressure sealing processing process by the pressure sealing processing apparatus in a case where an instruction to perform the pressure sealing processing process on the recording material of which the surface is not coated is included in the instruction from the user that is accepted via the input unit.

13. The image forming system according to claim 12 , wherein
the input unit includes a display unit that displays information, and
the control unit configured to perform warning display on the display unit in a case where an instruction to perform the pressure sealing processing process on the recording material of which the surface is not coated is included in the instruction from the user that is accepted via the input unit.

14. The image forming system according to claim 13 , wherein the control unit is configured to control the display unit to display, as the warning display, information
