Instructions and Help about compress pdf grayscale

Hey I'm salmon I do design and in the video today I'm showing you how to export your portfolios at high quality with a low file size last week I reviewed some of your portfolios and I made a request on my website to only submit portfolios that were 5 megabytes and under and I got the impression from you guys that it's really tricky to do that there are two reasons why I asked for that one is companies do that in the real world and they put a file limit on and the second one is it gave me an excuse to make this video today so in the video today I'm going to show you how to export a large portfolio with high quality images for under 5 megabytes and that's going to allow companies to use your portfolios in the real world as well the reason why companies do this is because they might have HR team within the company that has file limits on their emails so they can't get any files higher than 5 megabytes and there are so many other reasons for companies doing this as well and it's really important if they do quote a file limit you need to stick to that and make sure it's definitely under that because if you don't do that then it shows that you can't follow instructions and you're already not the top of the game for the portfolio list anyway so in order to do this I've made a really quick portfolio in InDesign here and I just used some images from unsplash some some open source free images it's the standard sort of you know there's nothing special about this portfolio but it's got the bare bones there images and text which is...


What are the best ways to compress or shrink a large PDF file?
CMYK-Colormanagement Files *.icc are often . For a presentation you do NOT need CMYK-colormanagement. Just convert everything in your file to sRGB and include this .icc-profile drop the other CMYKs. You can do this with Acrobat Pro or DC. A single CYMK-Profile like ECI ISO coated v2 takes up to 12 MB. A simple RGB Profile just about 5 KB. If you don any .icc-Files your PDF will look weird on Wide-Gamut Screens. ResolutionnForget about this 72 dpi-stuff. For screen purpose take 15 ppi. So you allow others to zoom in a bit and the images stay sharp. In fact resolution isn such a killer .icc-files are and this without any visible 15 ppi you allow others to make copies on a homeprinter or laserjet. The CMYK-printer will call you nuts with this file. Saving in higher PDF-StandardsnThis allows better internalpression of the PDF-streams yes Ask me about joboptions. Those files consist of settings for Acrobat Pro Do not forget to tell me the utilization. A optimal CMYK-Print-File is something very different to a presentation. Haha and it different here in europe too. We use ECI ISO coated as a general CMYK-output ICC For all of those who need fact and numbers in a shot termnI made tests with the same PDF-File written by InDesignnPrinting purpose with CMYK .icc-Data 1.4 MBnScreen purpose with sRGB 15 ppi JPG 8% 35 KB
How can I increase the image quality in a PDF?
Can you please add details to your question since it's almost impossible to answer with anything but a guess.n What software are you using to create the PDF? Without the information above my best guess is that you simply need to use a higher resolution s lower resolution to keep the file size low. If so you could turn that option off or increase the resolution.
How do I compress a PDF of size 300 MB to a reasonable size?
Adobe offers the best option to optimize (in this case to reduce size as well) using its PDF Optimizer tool PDF Optimizer provides finer control for reducing the size of PDF files. For most users the default settings will provide the best reduction in file size. Optimizer saves space by removing and duplicate fontspressing s can result in poor quality that is not suitable for printed materials. Always check the quality of your optimization beforemitting to saving the changes. Step #1 Open the PDF Optimizer tool. From the File menu choose Save As and then Optimized PDF. You can also launch the PDF Optimizer through the Advanced menu. Step #2 Audit your PDF size. Click the Audit space usage button to see a breakdown of what is taking up space in your PDF file. This will allow you to see if your s unaltered. When optimizing s to grayscalepress downsample and lower the quality. When optimizing fonts un fonts that you know all of your readers will have. For example if you are sending the PDF to people at your school they most likely will all be using the same system to read it so those fonts do not need to be . Step #4 Press OK. Your PDF will be converted using the new settings. You can check the new size by saving the file or by opening the PDF Optimizer again and clicking Audit space usage button. Alternatively you can use a number of online PDF optimizer tools but the size of your PDF file will make it buying premium services mandatory.
What kind of content are the causes of more or less size of a PDF file?
Certainly the of content that takes up the most space would be upressed raster pression (eg. JPEG) is good for some images but really bad for others. Are the fonts associated with the ? And if so are they subset or full ? What colorspace(s) are being used? CMYK and Spot color data (any object ) take up more space than RGB or Grayscale data. PDF also supports audio video and 3D data - all of which can potentially be large when fully or notpressed properly. And then there are all the non-visual things that can be present in a PDF that would take up space Metadata Structure & Semantic information Navigation aids etc. But at the end of the day - none of this is PDF specific. These are the same questions you would ask for Word or Keynote or EPUB or any other format. PDF just has lots more options for both increasing and decreasing file size.

How does a PDF compressor give the same quality with a lower size?
When youpress a PDF there is no information lost in the process instead thesepressor reorganizes the data to help it be more efficient when storing. This is possible because of PDF lossless feature. Unlike in photos wherepressors reduce the size and make it look pixelated PDFpressors only remove duplicate codes or fix disorganized data. Since photos and media are often the reason for large file size it is often the one affected whenpressor tools begin the process. In some PDFpressors like DeftPDF s there is also an option to optimize quality changing image resolution or turn it into grayscale if you really need the PDF to be smaller in size.
How do I save or convert a color PDF file to a black & white file?
If you are talking about more than just printing but actually want the digitial instance to be absent of color why I do not know there are several ways however the simplest is just to print to PDF and change the print from default and or color to black and white. Keep in mind though if many soft tones are used they might in black and white or gray scale be indistinguishable eg pastel light hues will all be a kind of greyish white so pastel yellow in a light tone and pastel blue in a light tone would be very similar in grayscale. The easiest generic non-application specific based method is simply to print to PDF in black and white. For Adobe Acrobat which is what most use for PDF files as it has industry dominance If you want a veryplex method Distill to a PDF then in Acrobat go to tools Print Productionconvert colors Device gray Convert Profile grey gamma 2.2 don't profile. Use advanced output preview to toggle the black separation on and off to confirm the file is black only. Adobe Community. However I would save yourself the headache and just print to PDF and change the print setting to black and white this works universally and just creates a new instance which is going to happen anyway and of course if you are going to change the version like that you are going to want to save it as a different version. No matter how advance the technology bes nor how small nor how multifunctional keep in mind aputer is basically two things a huge file cabinet and a calculator. When ever you are talking about datastructure which in its simplest most basic sense is just organizing things into smaller and smaller files in a huge file cabinet you want to ask your self if you were doing it physically what would you do for example if forgetting for a moment all aboutputers you drew a picture in color and I was like this is great but I need it in black and white can you redraw and you did would you then burn the color copy because some one wanted it in black and white.
What are some tips or websites where I can learn everything that goes in to making book covers?
A good page Beginner Ge To Book Cover Design Some other general rules are Learn some design. Photoshop Illustrator CorelDraw or even free source software like Gimp. Learn to use it. Do not design your book cover in Microsoft Word. Unless you are doing something that calls for a special size stick with one particular books size. I usually go with 6 x 9 unless there are more than 3 pages. Then I go with 8.5 (or ) x 11. Make sure your spine is calculated correctly. I use cream paper because the thickness rounds out to exactly .oo25 making it easy to calculate. Bright white paper is .2252. The reason you want an easy calculation is because a lot of software will end up rounding off. .2252 bes .23. In large books this may lead to the measurement being off enough to mess with the s. If you have a book with less than 125 pages do not put on the spine. 9 out of 1 times the printer will get the placement wrong or the will be too small to read. Unless you are a color expert use RGB over CMYK. Pretty much all printers now accept RGB after going digital. Back in the day you had to covert to CMYK first. CMYK can be unpredictable when printing and your colors will change if converting from RGB. With RGB you pretty much get what you see on the screen (so long as your screen is calibrated correction). And don't use color separation. When digital printing first took off printers used digital for color covers (which were cheaper) but would still use offset printing for the page interiors which only prints black. Even if the interior pages just had grayscale they would switch over to digital which at the time costs about 5ua2 more per page (same as color offset for interior) which added up quickly. But nowadays pretty much everything is done in digital and the prices havee down significantly. Use a bleed around you cover even if your s and fonts are within the file itself in the settings. It is easy to send one file to the printer than multiple files. Less things can go wrong. Be sure to flatten all your . You can do this usually by selecting the entire cover in case you have to make corrections to the makes the PDF smaller and helps avoid any unforeseeable color problems. Sometimes the printer will flatten the s or color in the book. If you decide to print in color later you won't have to change anything in the book file. Do notpress your has a lot of fine detail like a photograph then you may to supersize it. But above 12 is unnecessary. The cover file typicallyes out at around 1 to 2 mb. The interior file is usually no more than 6 to 1 mb. Use these same standards whether your cover is for print or an ebook.
