Instructions for Authors

These instructions have been updated on the 24th April 2021.

Some Basics

Each author who is accepted for publication in the C&C’21 proceedings will need to go through some simple steps. This page describes these steps.

The most important task is for each accepted author to transform their paper, pictorial, artwork report, poster, tool demo report and graduate symposium submission into the format needed for the C&C21 conference proceedings. To do this you, the authors, can continue to work in either Microsoft Word or LaTeX.

To support you in this process, ACM has been working hard to create a usable and accessible experience for Microsoft Word authors, while adding new features to archival formats. More information about this and how ACM prepares publications can be found at

At the same time, ACM continues to revise the Primary Article Templates for LaTeX authors, to improve their usability, functionality, and accessibility. To ensure 100% compatibility with The ACM Publishing System (TAPS), please restrict the use of packages to the list of approved LaTeX packages when using the Primary Article Template to your document.

You can find more background information about ACM processes at the bottom of this page.

Your Submission Process so far

So far, you have completed STEP 1 and STEP 2.

During STEP 1, all authors submitted manuscripts for review in a single column format. Authors using Microsoft Word wrote papers using the Submission Template (Review Submission Format), and no additional formatting was required. Authors using LaTeX wrote papers using the latest version of the Primary Article Template – LaTeX, and used the “manuscript” call to create a single column format.

During STEP 2, all authors submitted their papers, pictorials, artwork reports, posters, tool demos and graduate student symposium submissions for review.

Now, your submission has been accepted. Again, congratulations. You are now at STEP 3.

Preparing All Accepted Submissions for Publication

STEP 3: To ensure that your revised submission satisfies the reviewer comments, upload your revised submission to PCS. If your submission was conditionally accepted, also submit a separate document describing the changes made. Your submission should be a PDF file using the same template that should have been used for the original submission for your track. The revised submission should be de-anonymized. In addition, check that the paper title, abstract, and all author information entered into the PCS forms are correct and match exactly what is in the submission. The deadline for submitting the revised submission to PCS is May 4, 2021. You do not need to submit the video presentation. It will be submitted later (tentative deadline of June 1).

The co-chairs of your submission track will check your submission. You will receive an email if any further changes are needed. If no changes are needed, the co-chairs will authorise the submission for publication.

Once the co-chairs authorize the submission for publication, you will receive an email from the ACM e-Rights system. The e-Rights form will only be sent to the contact author, so it is important that this person is able to respond to emails and complete the form. This email will come from  Please remain alert for this email after your acceptance notification as it may be sent to spam. Ensure that all information such as the paper title, authors names, and emails match exactly how you want this to appear on your final publication. Any mismatches could delay the publication of your paper.

There are two separate publication processes from this stage forward. One is applied to all types of submissions apart from pictorials. The other is applied only to pictorials. Please note your type of submission, and follow the correct process.

Preparing Each Paper, Artwork, Poster, Technical Demonstration and GSS Submission for Publication

STEP 4 for authors using Microsoft Word. Upon notification of final acceptance, you should download the ACM Primary Article Template – Microsoft Word. Please choose the correct template version based on your platform: [MAC 2011, MAC 2016, or Windows] and save the .zip file to your local machine. Open the zip file and save the template file to your machine and then follow these instructions to attach the ACM Article Template to your accepted submission version and prepare your revised submission (still in single-column format) for validation.

STEP 4 for authors using LaTeX: Proceed directly to STEP 5.

STEP 5: To submit your source file (either in WORD or LaTeX) for production processing, you will receive an email notification with instructions to upload your Camera Ready (finalized) source file set to The ACM Publishing System (TAPS). Please make sure that you and your authors approve in their email settings to ensure that all messages from TAPS are received. Download these instructions for the information on how to use TAPS. TAPS will process your paper and auto-generate proofs of your article for your review. Final review and approval of your submission rests with the C&C’21 Publication Chair. The deadline for completing this process is June 11, 2021, although the publication chair will be chasing authors to complete before this date.

The output formats (the traditional PDF proof and a new HTML version) provide enhanced accessibility, responsive formatting, and reusable components (i.e., extractable math) within the HTML output.

Note: While you may need to make corrections to the output in TAPS, you MUST revise the file which was uploaded to TAPS. Do NOT  reupload new versions of your locally kept source files. There is no requirement to update the version in PCS at this stage. The version submitted to TAPS will be the official version that is entered into the ACM Digital Library.

For all questions regarding the overall publication process and its deadlines, please contact
Please note that the conference organisers are not able to address specific issues related to either the templates or the e-Rights forms.

For technical issues with the Word or LaTeX templates, please contact

For issues with ACM’s e-Rights forms, please contact

Preparing Each Pictorial for Publication

STEP 4: Upon notification of acceptance, you will produce the publication version of your submission. Unlike other forms of submission, pictorials should be published using the same templates that were provided for the submission. ACM is currently moving to a new publications workflow for papers is accessibility, and pictorials authors are required to be sure that they produce accessible work. Please be sure that “Enable Accessibility and Reflow with tagged Adobe PDF” is checked when you create your PDF submissions file. Please be sure that all images have correct associated Alt Text. Please see:

Upload your final source files and PDF version of the pictorial to PCS. Ensure that all the information, such as the paper title, abstract, and author names and affiliations listed in the PCS form are correct and match exactly the content of the paper as requested. There is no STEP 5 for pictorials publication.

LaTeX Collaborative Authoring Tool on Overleaf Platform

ACM has partnered with Overleaf, a free cloud-based, collaborative authoring tool, to provide an ACM LaTeX authoring template.

  • Overleaf is a collaborative platform: Authors can easily invite colleagues to collaborate on their documents. 
  • Authors can write using ‘Rich Text mode’ or regular ‘Source Mode.’ This is useful for cross-disciplinary collaboration in the cases where some authors prefer to write in LaTeX while others might prefer a Word processing format. 
  • The platform automatically compiles the document while an author writes, so the author can see what the finished file will look like in real time.  
  • The template allows authors to submit manuscripts easily to ACM from within the Overleaf platform.

The ACM LaTeX template on Overleaf platform is available to all ACM authors  at

Best Practices

Please see the ACM’s best practices guidelines for Microsoft Word, LaTeX, and The ACM Publishing System (TAPS). These have been compiled and will be updated regularly to serve as a reference to help authors prepare their text for publication by the most efficient means possible.

If you wish to provide feedback on the templates, documentation, or workflow, please contact

  1. For Microsoft Word best practices, please see embedded instructions within the formatted 2-column example of the submission template which includes alt-text for floats
  2. LaTeX best practices; also available in PDF
  3. The ACM Publishing System (TAPS) best practices; also available in PDF


ACM is committed to publishing in an accessible format ( that permits all its readers to have the content presented to them in a thorough and useful way. ACM needs the assistance of its authors to help achieve this goal. It is important that ACM authors provide descriptions for figures in their content so that ACM readers with visual impairment can be given equivalent text-based information for images. Figure descriptions are complementary to figure captions and should not repeat the same information. Refer to writing figure descriptions for guidance on writing descriptions and insert them into your manuscript in different versions of Word.

ACM Production Workflow Background

Microsoft Word: ACM has been working hard to create a usable and accessible experience for Microsoft Word authors while adding new features to archival formats. We have completely changed our approach to the production process to achieve ACM’s goal of a publication portfolio available in flexible formats with accessibility features. More information about the motivation behind this change and how we prepare publications can be found at

Working with volunteers from the SIG and journal communities, ACM has developed a new, easier to use Microsoft Word authoring format and workflow that completely replaces the previous formats that were difficult and unusable. This new approach enables authors to concentrate on their content rather than print output formatting, and alleviates the time needed to prepare the text for submission.

LaTeX: ACM continues to revise the Primary Article Templates to improve usability, functionality, and accessibility as needed. Please review the Primary Article Templates documentation in section 2 of this page for the latest version and update history. To ensure 100% compatibility with The ACM Publishing System (TAPS), please restrict the use of packages to the list of approved LaTeX packages when using the Primary Article Template to your document. The approved package webpage also provides information on how to submit additional LaTeX packages for review and adoption.

Should you have any questions or issues going through the below steps, please contact support at for both LaTeX and Microsoft Word inquiries.
