Hi. In regards to renders. Would like to ask how to work out and set the following:
resolution size,
ratio,
dpi,
file type,
Portrait or Landscape,
for large B1, B2, B3 size posters?
I've read 300dpi is ideal for poster resolution.

In a sense, all of that is determined by what options the printer gives you. From there, the DPI determines the resolution of your render. In the example of an 11"x17" poster at 300 DPI, the aspect ratio is 11:17, the resolution of the render is 300 times each of the dimensions, or 3,300 (11 x 300) x 5,100 (17 x 300).
300dpi is the preferred resolution for a lot of print. However, for posters you can get away with less based on the fact that the viewer will usually be standing further away from it.

So say for a B2 size poster: (300dpi x 27.83) = 8,349 (300dpi x 19.69) = 5,907.
I set the Resolution at: 8,349 x 5,907
I set the Ratio to: 27.83 : 19.69 or 28 : 20 rounded?
I wonder how long it would take to render?
B poster sizes
How much less DPI do you think?
@SofaCitizen
Well, it would heavily depend on how far away the audience is and how long they will be studying it. For example, the billboards you might see overlooking a road/highway would not be anywhere near 300dpi since the only ones to see it up close would be the people putting them up - everyone else would be viewing from many metres away.
While I do work for a printing company I don't get involved in a lot of the poster/large-format jobs we do so my personal experience there is very limited. However, as a very rough guide you can see the table on this page which lists a suggested minimum resolution by viewing distance. Although, as was already mentioned, the print company that you are using may want/demand something higher so would probably be worth checking with them first.
Leave the ratio alone, it is just saying the same thing as the size (it is useful if you want to resize a render while preserving the proportions, with the constraint button on, or if you know the proportion and just want to set one of the dimensions - you want a specific size, however, so it will be useful only if you need to change the PPI value.
If wanting to print a B1 poster at 300dpi split into 2 images in portrait orientation. Effectively 2 x B2s combined and have bleed areas. How is the render set to Full Bleed Size dimensions?
Full Bleed Size 19.84" x 27.99" 504 x 711 mm
Document Trim Size 19.69" x 27.83" 500 x 707 mm
Safety Area 19.53" x 27.68" 496 x 703 mm
If wanting to print a B1 poster at 300dpi. How is the Render set at Full Bleed Size dimensions in Daz Studio?
Full Bleed Size 27.99" x 39.53" 711 x 1,004 mm
Document Trim Size 27.83" x 39.37" 707 x 1,000 mm
Safety Area 27.68" x 39.21" 703 x 996 mm
DPI is dots per INCH, so metric isn't applicable here. You'd multiply both dimension by 300, giving you 8,397 x 11,859...which is a problem, because I think DS caps out at 10,000px on either axis.
Have to go smaller then. Thinking of going smaller anyways. B1 and B2 posters can get expensive.
DP
I'm thinking of going A2 poster size. 16.5in x 300 = 4,950 x 23.4in x 300 = 7,020.
How do I set the render to portrait and landscape in Render Settings.
What do I set the ratio to or how to turn it off?
@Gordig @Richard Haseltine
Turbn off the constrain Proportion button, thentyype the numbers into the Pixel Size width and height boxes (the Aspect Ratiowill then update as you do so). You can just type 16.5*300 and 23.7*300, DS will then do the actual calculations (input boxes can evaluate script commands).
You don't "turn off" the ratio so much as you change it.
You'll get by with a working ratio of 4:5.7
Set the pixels for your test render to something like 2048 x 2918 (that is more or less what 4:5.7 gives you, in terms of working space)
You didn't say what printer and/or materials you are sending this to. Just as an example some of the common places to print like Staples, Walmart, Cafepress and so on will have a limited selection in terms of paper type, weight and finish. And if you are sending to plastic materials (sticky wall posters, vinyl - like Cricut, or shower curtains or window decals etc.) or cloth (cotton, linen, canvas?) your colors may shift... ergo different materials may require slight adjustments in the source art you send to the printer or output engine.
If you're planning to sell just the artwork, eg. something that people may download (hopefully for a fee, like through Deviantart or Patreon) bear in mind that discerning customers may want a highter resolution, so give them something closer to 4,096 pixels across, at 200 or 300 dpi. The downside of giving out big files is that the more information (eg. data, resolution) a purchaser has, the better equipped he or she will be to repurpose your work in some way. Possibly in ways you may not like. Not everyone plays by the rules.
What you're writing contradicts what Richard Haseltine is saying. Which is correct?
I'm wanting to print maybe A1 or A2 in landscape on poster paper either 160gsm or 200gsm at a office supply store called Officeworks. They have a bloody big Canon Commercial printer.

Richard is correct . If you disable "constrain proportions" and type in your dimensions, it will automatically adjust to the aspect ratio of the dimensions you entered.
Sorry, I didn't read Richard's comment. My bad? Perhaps.
The "correct" method will less to do with technicalities and more with fluid, day to day issues. Whatever you think gets you to the place you want to be sooner, and on budget or close to it.
I think that at this point in time your most important workflow tools are a couple of sheets of letter-sized paper and a 2B pencil, or a newsprint pad and a Sharpie felt pen.
Review what jobs Officeworks did for you or your friends in the past, and what the source art was for that stuff. Or look at their samples and try find out about the source art. Is your poster idea a bigger job or smaller? What about the UI and overall UX? Are you submitting on-line (that sometimes forces you to work within narrow guidelines) or are you going there in person? You may find yourself making adjustments to other parts of the project as you encounter bigger variables and issues than the aspect ratio and the paper size.
That's okay. I wasn't sure. All info is beneficial.
I will go into the store and converse with the correct experienced staff. Some have no clue. I have had images printed from them many times before. Today I asked them with size they can print on the huge printer.
