Print agent transfer assemblies

1. A print agent transfer assembly comprising:

a print agent transfer member to receive a first layer and second layer of print agent, the first layer and second layer defining a multilayer image; and

an energy source to provide energy at a first predetermined intensity level to the first layer and to provide energy at a second, different, predetermined intensity level to the second layer.

2. The print agent transfer assembly of claim 1 , wherein the first predetermined intensity level is predetermined based on at least one of:

a type of print agent in the first layer of print agent;

a number of further layers to be received at the print agent transfer member over the first layer of print agent; and

a thickness of the first layer of print agent.

3. The print agent transfer assembly of claim 1 , wherein the energy source comprises at least one of a plurality of light emitting diodes (LEDs) and a plurality of vertical cavity surface emitting lasers (VCSELs).

4. The print agent transfer assembly of claim 1 , wherein the print agent transfer member is to receive the first and second layers of print agent before the first and second layers of print agent are transferred simultaneously to a substrate.

5. The print agent transfer assembly of claim 1 , wherein the first predetermined intensity level is lower than the second predetermined intensity level.

6. The print agent transfer assembly of claim 5 , wherein the first predetermined intensity level is zero.

7. A print agent transfer assembly comprising:

a print agent transfer member to receive a first layer and second layer of print agent; and

an energy source to provide energy at a first predetermined intensity level to the first layer and to provide energy at a second, different, predetermined intensity level to the second layer;

wherein the print agent transfer member is to transfer the first layer of print agent to a substrate before receiving the second layer of print agent.

8. A method comprising:

determining, on a layer-by-layer basis, a level of heat flux to be supplied to a layer of print agent of a multi-layer image;

receiving the layer of print agent on a transfer member; and

supplying the determined level of heat flux to the layer of print agent on the transfer member.

9. The method of claim 8 , wherein determining the level of heat flux comprises determining the level based on one of:

a type of print agent in the layer of print agent;

a number of further layers of print agent to be received at the transfer member over the layer of print agent; and

a thickness of the layer of print agent.

10. The method of claim 8 , comprising:

receiving a further layer of print agent on the transfer member on top of the layer of print agent;

determining a further level of heat flux to be supplied to the further layer of print agent;

supplying the determined further level of heat flux to the further layer of print agent on the transfer member; and

transferring the layer and the further layer simultaneously onto media.

11. The method of claim 10 , wherein the level of heat flux is lower than the further level of heat flux.

12. The method of claim 10 , wherein the level of heat flux is zero, and the further level of heat flux is non-zero.

13. A method comprising:

determining, on a layer-by-layer basis, a level of heat flux to be supplied to a layer of print agent;

receiving the layer of print agent on a transfer member;

supplying the determined level of heat flux to the layer of print agent on the transfer member;

transferring the layer of print agent to media;

receiving a further layer of print agent on the transfer member;

determining a further level of heat flux to be supplied to the further layer of print agent; and

supplying the determined further level of heat flux to the further layer of print agent on the transfer member.
