I think you are confusing Peter’s tutorial with my video. My video is an overview of the Pan h and Pan v controls. It was not intended to be a direct guide to producing large renders. However, if as I said, you could provide me with the dimensions you want your final render output at then I could provide you with the steps needed to render at that size - using Pan h and Pan v.
Sorry about that.
I want to do 18x12 at 200 dpi.
would need to know, final output size. pixels x pixels.
The reason I specified pixels by pixels because without knowing your printer I would not know how many dots were required to represent one pixel value.
As I was saying to Erich just the other day…

I think I am going to beg Horo to write a little explanation for this since he has done such print tests and we are forever running into this dpi issue. Just, I think because it is shown in the render to disc options, it is given credence - also printers who should know better give it credence.

You cannot convert a pixel directly into a dot (well should not)
Suppose a dot on a printer is either black, yellow, cyan or magenta.
And to get the colours, the dots are staggered. So the calculation is how
many dots are required to make the same information value as one pixel?
Otherwise you are just wasting pixels - wasting information and render time.
Suppose DPI B,Y,C,M on or off, 1,1,1,1 max values. RGB 255,255,255 you need
a more 1,1,1,1’s to express the same information as 255,255,255 will. So
DPI will be much higher than PPI.
DPI is dots per inch not PPI pixels per inch.
The printers should be able to say, how many PPI is appropriate, but in my
experience, printers can’t be [bothered] to think about this problem and as a
result over specify and talk in DPI.
So your dimensions would give me a total of printer dots by printer dots, but I don’t have any conversion for how many dots make a pixel. If you choose 1:1 you will have to make huge renders and then be throwing away 50% or more of that information when you print.
Do you see how wasteful this could be?
