Adobe still owns it. The iso open source reference code is for older versions of the pdf standard. Most 3rd party pdf writing emulators are adequate for home use, but you may get crazy results if your files are not set up correctly .
Sorry, but you don't know what you're talking about.
The ISO standard describes the PDF file format. It is not "source code". Therefore it makes no sense whatsoever to speak of "open source reference code". That's not what ISO does. It's a standards body.
ISO 32000.1 is basically equivalent to PDF 1.7. There is no PDF 1.8. Adobe has published a document describing extensions to ISO 32000.1. supported by Acrobat 9, Reader 9, and LiveCycle ES 8.2. These extensions are primarily to support interactive features, and AFAIK, there are none that affect the imaging model.
If the OP is going to be printing large posters, then as much of the artwork as possible should be created in a drawing program (Adobe Illustrator, Corel Draw, etc.) and not a paint program. That way the artwork is described as resolution-independent mathematical descriptions (curves and lines) rather than as pixels, and will scale up smoothly to whatever the size of your final output. If the artwork is created as pixels, then it looks worse and worse as the size is scaled up because you've fixed the maximum resolution at the time you created your canvas. Sorry, but the advice to use a paint program to create the poster just demonstrates ignorance.

I'm not going to argue. I was always wondering about the reason influx of cheap pdf writers.

This is why i said that the image needs to be 300 dpi at final output size. I also said the file will be huge. Ideally a vector program is the way to go. Although Indesign, Illustrator and even quark can now create many of the same effects as photoshop, sometimes photoshop is just the way to go. In these days of cheap 20gb flash drives, size really isn't as much of an issue as it use to be.

That's why I suggested asking the printer what they wanted, I used to do all my own ads and I didn't have Adobe so I couldn't send them .ai but I had everything I used in my own programs default vector/path proprietary file. Sometimes getting that information was like pulling teeth. I know the printers have to deal with the public a lot so I guess they think everyone is an idiot, all they need to provide is the physical size and the DPI and a standard bitmap image should be fine. Sometimes I wonder if they know what they are talking about becsue my Sister in law used to do some photography for small newspaper here and they would not accept 12MP images because they were 72DPI as if there was some difference between them.
Hello! I need to design a few full color posters that will go to print. Can anyone recommend an easy to use graphic design program? I need something that is powerful enough for professional printing purposes but easy enough to learn for a layperson.
Thanks!
Canva might be a good fit! It's an online graphic design platform known for its user-friendly interface and drag-and-drop functionality. It offers a wide range of pre-made templates, stock photos, and design elements, making it easy to create professional-looking posters without needing extensive design knowledge. While it lacks the advanced features of industry-standard software like Adobe Illustrator, it allows exporting designs in high-resolution formats suitable for professional printing. Consider supplementing your learning with a beginner-friendly graphic design courseto gain a deeper understanding of design principles and techniques.
